In order to meet the digital requirements and high fidelity of power amplifier, MCU is been used as the core, and AC/DC of the chip is been used sample conversed circuit from analog to digital. The control equation model is established to design modular and debug, and to choose the appropriate features state step by step. The front part of Two-stage Dual-sampling feedback amplifier is directly coupled amplify the weak signal voltage up to the highest 3.3V without distortion. At the secondary level the front part of signal power amplifier is enlarged by field effect push-pull tube. Through computer process, the output screen show signals about the power of the amplifier, the output power and the machine efficiency index. The test results show that the circuit has a good pass-band. AC/DC access signal can dynamically change PWM modulation according to different loads. The state control equation and mapping algorithm improve the flexibility of two-stage dual-sampling feedback amplification.
