ATOS Amplifiers

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.

ATOS Amplifier Basic Introduction:

ATOS amplifiers are devices that increase signal amplitude or power. They are important components in signal processing tools in automation technology. An amplifier's amplification function is achieved by controlling the energy source with the input signal; the power consumption required for amplification is provided by the energy source. For a linear amplifier, the output is a reproduction and enhancement of the input signal. For a nonlinear amplifier, the output has a certain functional relationship with the input signal. Amplifiers are classified according to the physical quantity of the signal they process: mechanical amplifiers, electromechanical amplifiers, etc.

ATOS amplifiers are important components of transmitting devices in communication systems. Based on their operating bandwidth, they are divided into narrowband high-frequency power amplifiers and broadband 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. Broadband high-frequency power amplifiers use a transmission line transformer or other broadband matching circuits as the output circuit, hence 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 classified into three operating states—A, B, and C—according to 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.

Basic Structure of an ATOS Amplifier:

ATOS Amplifier

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

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 of the input signal do not contribute to the output voltage.

Two sinusoidal signals, both 1 Hz in frequency and 90 degrees out of phase, multiplied together by a multiplier, result in a sinusoidal signal with a DC bias.

If a 1 Hz signal and a 1.1 Hz signal are multiplied together, the result is a modulated signal with a sinusoidal profile and a DC bias of 0.

Only signals with the same frequency as the reference signal will produce a DC bias at the multiplier output; other signals will produce AC signals at the output. If a low-pass filter is added to the multiplier output, all AC signal components will be filtered out, leaving a DC component that is simply proportional to the amplitude of the specific frequency component in the input signal.
