Because of the high price of marketable charge amplifier, a low price charge amplifier was developed. It is based on the principal of the circuit of the charge amplifier. Simulation and experimental test show that this circuit is feasible. It has advantage of good transient stability,low price and anti-disturbance character,zero shift is less than 20mV.
