Abstract
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 amplifier, an input capacitor, a feedback capacitor 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 and, thus the integration produces less signal degradation.
