Filter circuit module of higher order, e.g. low pass filter circuit, with capacitor for filter order, preferably with transformer function of filter circuit module

摘要

Filter circuit module (200) of higher order comprises capacitor (205-207) for each filter order, e.g. second and higher order. Each capacitor is included in integrator, provided for filter order. Preferably, at least one integrator incorporates an additional transistor. The transfer function may contain adjustable zero position formed by capacitor and transistor, as well as double pole.
