ABSTRACT:
In a filter circuit of a capacity ground type in which the capacitance connected to output terminals of integrators is grounded, output signals are fed back from multiple stages of integrators to respective input stages of a subtracter which constitute a differential couple with input stages of the first stage integrator, and in the subtracter input signals are subtracted by fed back signals of the multiple stages and are then outputted. It is thereby capable to constitute a high-pass filter in a filter circuit of the capacity ground type with ease.
