Basic Structure of ATOS Amplifiers

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 "Low-Frequency Electronic Circuits" course, amplifiers can be classified into three classes (A, B, and C) based on their current conduction angle. Class A amplifiers have a current conduction angle of 360°, suitable for small-signal, low-power amplification. Class B amplifiers have a current conduction angle of approximately 180°; Class C amplifiers have a current conduction angle of 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, Class C amplifiers exhibit excessive current waveform distortion, 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 sinusoidal waveform, resulting in minimal distortion.

ATOS Amplifier Basic Structure:

The ATOS amplifier takes the input signal as the test signal, amplifies it, and then uses it as a bandpass filter. This signal, along with a reference signal, is input to a multiplier. The result is then filtered by a low-pass filter before being output.

ATOS Amplifier Main Principle:

An ATOS amplifier is essentially an analog Fourier transform. The output of the lock-in amplifier is a DC voltage, proportional to the amplitude of the input signal at a specific frequency (the 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 90 degrees out of phase, multiplied together 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 a DC bias of 0.

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

Main applications of ATOS amplifiers:

ATOS amplifiers are primarily used to detect weak signals with very low signal-to-noise ratios. Even if the useful signal is submerged in noise, or even if the noise is much stronger than the useful signal, knowing the frequency of the useful signal allows for accurate measurement of its amplitude.
