ABSTRACT:
A switched-capacitor circuit for sampling a pair of differential input signals includes a first bootstrapped switch and a first non-boosted switch connected in parallel between a first output terminal of an amplifier and a first feedback node of the switched-capacitor circuit to form a first feedback signal path and a second bootstrapped-switch and a second non-boosted switch connected in parallel between a second output terminal of the amplifier and a second feedback node of the switched-capacitor circuit to form a second feedback signal path. The first and second non-boosted switches are controlled by a first clock signal and the first and second bootstrapped switches are controlled by a second clock signal where the second clock signal is the first clock signal delayed by a predetermined amount.
