Abstract
A gain amplifier may have a differential amplifier with feedback capacitors; a switched input stage having first and second outputs coupled with the differential amplifier, and having: first and second capacitors, a first input receiving a first signal of a differential input signal; a second input receiving a second signal of the differential input signal; a first plurality of switches controlled by a first clock signal to connect the first terminals of the first capacitor with the first or second input, respectively and to connect the first terminals of the second capacitors with the second and first input, respectively; and a second plurality of switches controlled by a phase shifted clock signal to connect the second terminal of the first capacitor with a first or second input of the differential amplifier and connecting the second terminal of the second capacitor with the second or first input of the differential amplifier.
