Abstract: A differential amplifier circuit that exhibits low temperature drift and a wide dynamic range includes a differential amplifier having first and second input terminals, first and second circuit nodes operatively connected to the first and second input terminals, respectively, a differential input signal pair, first and second sampling capacitors and a switching circuit. During a first operational phase, the switching circuit connects, a first plate of the first capacitor to a first input signal of the differential input signal pair, connects a first plate of the second capacitor to a second input signal of the differential input signal pair, and connects second plates of the first and second capacitors to a reference voltage.
