Abstract

See full text

A filter circuit for generating a filtered signal includes a first filter unit, a second filter unit, and a negative feedback resistor. The first filter unit includes a signal input unit that receives signals, a signal output unit that outputs the filtered signals, and a non-ideal integrator and a first ideal integrator that are connected in series between the signal input unit and the signal output unit. The second filter unit includes an ideal integrator that is negative feedback-connected to the non-ideal integrator or the first ideal integrator. The negative feedback resistor is connected between the signal output unit and the signal input unit of the first filter unit.
