Abstract:
     A weighted gate integrator circuit for detecting weak signals features that an operating amplifier is used to perform the linear accumulation to the charge current of gate integrator circuit, and more than two weighting resistors are designed for the gate integrator in order to combine them to obtain different step weight values. It can be used for Faraday effect tester, vibrating specimen magnetometer, inductor or capacitor measuring instrument.
