The present invention is a charge amplifier that directly produces a low impedance voltage output proportional to the charge at its input. The invention consists of an operational amplified an input capacitor a feedback capadtor and a feedback resistor in a parallel configuration. The change amplifier of the present invention can be said to be a differentiator followed by an integrator so that the noisy differentiation process precedes the integration ani thus the integration produces less signal degradation.
