Abstract
An integrating filter circuit having a reference potential source for supplying the integrating filter circuit with a prescribed reference potential, a transconductance circuit provided with a differential circuit, a variable current source couple to the differential circuit and output means coupled to the differential circuit for outputting an intermediate voltage of the outputs of the differential circuit, a common feedback loop with a comparison circuit coupled between the output means and the variable current source so as to stabilize the intermediate voltage in reference to a reference voltage supplied to the comparison circuit and capacitors coupled between the variable current source and the reference potential source.
