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 amplifiers are important components of transmitting devices in communication systems. 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 frequency-selective circuits with frequency filtering capabilities as their output circuit, hence they are also called tuned power amplifiers or resonant power amplifiers. Wideband high-frequency power amplifiers use transmission line transformers or other wideband matching circuits as their 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 classified into three operating states (A, B, and C) according to their current conduction angle. Class A amplifiers have a current-carrying angle of 360°, suitable for small-signal, low-power amplification. Class B amplifiers have a current-carrying angle of approximately 180°; Class C amplifiers have a current-carrying angle of less than 180°. Both Class B and Class C are suitable for high-power operation. Class C has 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 large, therefore they cannot be used for low-frequency power amplification, but only 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, with very little distortion.

The main principle of ATOS amplifiers:

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

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

If a 1Hz signal and a 1.1Hz 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.

ATOS amplifiers are most widely used in electronic amplifiers. With the promotion of jet technology (see jet elements), the application of hydraulic or pneumatic amplifiers is also gradually increasing. 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. In addition, they are commonly used for impedance matching, isolation, current-to-voltage conversion, charge-to-voltage conversion (such as charge amplifiers), and to achieve a specific functional relationship between output and input using amplifiers (such as operational amplifiers).
