Summary:A differential feedback circuit with an active noise cancelation technique using a dual input differential pair. In the differential feedback circuit, a feedback voltage and a reference voltage connect to a primary input pair. Sensed noise at the inputs is put to a secondary input pair of the differential amplifier, which is inverted with respect to the primary input pair. In other words, the reference voltage, which may be subject to noise, connects directly to one terminal of the secondary input pair and through a low-pass filter to another terminal of the secondary input pair so that the noise, which may be coupled to the differential feedback circuit, cancels at the output of the differential feedback circuit.
