AI Technical Summary
Existing amplifier circuits have poor linearity, and the output signal is easily affected by subsequent circuits, making it difficult to achieve high-precision and high-stability signal processing.
A voltage-controlled AC circuit with feedback is adopted. Through the operational amplifier feedback loop and control loop, combined with the operational amplifier chip and voltage control chip, the signal can be accurately adjusted and stabilized. The microcontroller DAC chip provides a stable DC voltage signal to generate and adjust the output AC voltage waveform.
It improves the accuracy and reliability of the output signal, suppresses the influence of external environment and circuit factors, and achieves high-precision and high-stability signal processing.
