ATOS amplifiers are devices that amplify the voltage or power of input signals. They consist of vacuum tubes or transistors, power transformers, and other electrical components. They are used in various devices such as communications, broadcasting, radar, television, and automatic control.

Basic Introduction (Folded)

A device that increases the amplitude or power of a signal. It is an important component in signal processing tools in automation technology. The amplification function of an amplifier is achieved by controlling the energy source with the input signal; the power consumption required for amplification is provided by the energy source. For linear amplifiers, the output is a reproduction and enhancement of the input signal. For nonlinear amplifiers, the output has a certain functional relationship with the input signal. Amplifiers are classified according to the physical quantity of the signal they process, such as mechanical amplifiers, electromechanical amplifiers, and pneumatic amplifiers, among which electronic amplifiers are widely used. With the popularization of jet technology (see jet components), the application of hydraulic or pneumatic amplifiers has gradually increased. Electronic amplifiers are further classified according to the active devices used: vacuum tube amplifiers, transistor amplifiers, solid-state amplifiers, and magnetic amplifiers, with transistor amplifiers being the most widely used. In automated instrumentation, transistor amplifiers are commonly used for voltage and current amplification of signals, primarily in single-ended and push-pull forms. They are also frequently used for impedance matching, isolation, current-to-voltage conversion, charge-to-voltage conversion (such as charge amplifiers), and for realizing a specific functional relationship between output and input (such as operational amplifiers).

ATOS Amplifier Main Functions (Folded Edit Section)

1. A device that amplifies the voltage or power of an input signal, composed of vacuum tubes or transistors, power transformers, and other electrical components. Used in various devices such as communication, broadcasting, radar, television, and automatic control.

ATOS Amplifier Principle: High-frequency power amplifiers are used in the final stage of a transmitter. Their function is to amplify the high-frequency modulated signal to meet the transmission power requirements, and then radiate it into space through an antenna, ensuring that receivers within a certain area can receive a satisfactory signal level without interfering with communication on adjacent channels.

High-frequency power amplifiers are important components of the transmitting device in a communication system. Based on their operating frequency band, they are divided into narrowband high-frequency power amplifiers and wideband high-frequency power amplifiers. Narrowband high-frequency power amplifiers typically use a frequency-selective circuit with frequency filtering as the output circuit, hence they are also called tuned power amplifiers or resonant power amplifiers. Wideband high-frequency power amplifiers use a transmission line transformer or other wideband matching circuits as the output circuit, therefore they are also called untuned power amplifiers. A high-frequency power amplifier is an energy conversion device that converts DC energy supplied by a power source into high-frequency AC output. As known in the course "Low-Frequency Electronic Circuits," amplifiers can be divided into three classes (A, B, and C) based on their current conduction angle. Class A amplifiers have a current conduction angle of 360° and are suitable for small-signal, low-power amplification. The current-carrying angle of a Class B amplifier is approximately 180°; that of a Class C amplifier is less than 180°. Both Class B and Class C amplifiers are suitable for high-power operation. Class C amplifiers offer the highest output power and efficiency among the three operating modes. Most high-frequency power amplifiers operate in Class C. However, the current waveform distortion of Class C amplifiers is too high, making them unsuitable for low-frequency power amplification. They are only suitable for resonant power amplification using a tuned circuit as the load. Because the tuned circuit has filtering capabilities, the circuit current and voltage remain very close to a sine wave, resulting in minimal distortion.

2. A tool used to enlarge or reduce figures when drawing. Also called a magnifying ruler.

Historical Background

The invention of the first lock-in amplifier (LIA) by EGG PARC (the predecessor of SIGNAL RECOVERY) in 1962 marked a significant breakthrough in weak signal detection technology, greatly promoting the development of basic science and engineering technology. Currently, the continuous advancement of weak signal detection technology and instruments has led to its widespread application in many scientific and technological fields. Future scientific research will not only place higher demands on weak signal detection technology, but new scientific and technological developments will also, in turn, promote the emergence of new principles and methods for weak signal detection.

Early LIAs were implemented using analog circuits. With the development of digital technology, hybrid analog-digital LIAs have emerged. These LIAs simply use digital filters to suppress noise in the signal input, reference signal, and output channels, or they add analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and various general-purpose digital interface functions to the analog lock-in amplifier (ALIA). This allows for computer control, monitoring, and display, but the core phase-sensitive detector (PSD) or demodulator is still implemented using analog electronics, making it essentially an ALIA. Until phase-sensitive detectors or demodulators were implemented using digital signal processing, digital lock-in amplifiers (DLIAs) emerged. DLIAs have many significant advantages over ALIs and are highly favored, becoming a hot topic in weak signal detection research. However, in some special applications, ALIs still play an irreplaceable role compared to DLIAs.

Basic Structure (Folded Edit Section)

The input signal to be measured is amplified and bandpass filtered, then combined with a reference signal and input to a multiplier. The result is then filtered by a low-pass filter before being output.

ATOS Amplifier Main Principle (Folded Edit Section)

A lock-in amplifier is essentially an analog Fourier transform. The output of a lock-in amplifier is a DC voltage, proportional to the amplitude of the input signal at a specific frequency (parameter input frequency). Other frequency components in the input signal do not contribute to the output voltage.

Two sinusoidal signals, both 1Hz in frequency and with a 90-degree phase difference, multiplied by a multiplier, result in a sinusoidal signal with DC bias.

Multiplying a 1Hz signal and a 1.1Hz signal using a multiplier results in a sinusoidal modulated signal with zero DC bias.

An ATOS amplifier only outputs a DC bias at the multiplier for signals with the same frequency as the reference signal. Other signals output as AC. If a low-pass filter is applied to the multiplier output, all AC components are filtered out, leaving a DC component that is simply proportional to the amplitude of the specific frequency component in the input signal.
