Teacher, when designing this sensor amplifier circuit, the sensor output amplitude is at the mV level, the frequency is within 1KHZ, and the voltage is amplified to 0-5V. How should this circuit be de
I just started to learn how to use op amps. The project needs to amplify a small signal with a Vpp of 20mV (with a 1V DC bias) to 0~4V. I plan to use a bandpass filter to filter out high-frequency noi
