摘要： An electrical circuit which includes a filter bypass mode. The circuit includes an amplifier including an inverting terminal, a noninverting terminal and an output terminal, at least one first capacitor coupled to the inverting terminal of the amplifier through at least one first switch, and, at least one second capacitor coupled to the noninverting terminal of the amplifier through at least one second switch. The electrical circuit provides filtering when the first and second switches are in a first state, and when the first and second switches are in a second state, the electrical circuit provides substantially no filtering.
