The voltage amplifier circuit of the piezoelectric accelerator
The voltage amplifier circuit of the piezoelectric accelerator The voltage amplifier is an amplifier circuit with a high input impedance, as the capacitance change of the sensor output cable will make the output voltage change with it, so R is often used in the piezoelectric accelerating sensor with an amplifier inside it.
