The second capacitor 205 may comprise a first plate and a second plate. The second capacitor 205 may be connected to the first switch 225, wherein in the first plate of the second capacitor 205 is connected to the first switch 225 and the second plate is connected to the output terminal of the amplifier 200. In other words, the second capacitor 205 is directly connected between the first switch 225 and an output terminal of the amplifier 200.

The second integrator 115 may be connected to the output terminal of the amplifier 200 and may be configured to perform a second integration function on an output signal of the amplifier 200. The second integrator 115 may comprise any circuit and/or system suitable for performing integration, such as the elements included in the first integrator 110, as described above.

The second integrator 115 may generate and transmit a second integrator output signal to a second adder 135. The second adder 135 may perform an addition function on the second integrator output signal and an output signal of the buffer 140.

The first signal converter 120 may be configured to convert an analog signal, such as a signal (voltage) generated by the second adder 135, to the digital output signal V_OUT. In an exemplary embodiment, the first signal converter 120 may comprise any suitable quantizer circuit.
