What is a Charge amplifier?

A charge amplifier is an amplifier that converts a very small charge signal generated by a piezoelectric sensor, which is difficult to measure, into a proportional voltage signal. The charge signal generated by a piezoelectric sensor is exactly proportional to the pressure applied to it, so accurate measurement of this value is very useful. A charge amplifier can convert the charge signal generated by the pressure sensor into a voltage that is accurately proportional to the charge.
