ABSTRACT:
Exemplary embodiments of the disclosure include adaptively generating a bias current for a switched-capacitor circuit. An exemplary apparatus includes a first phase signal and a second phase signal operating at a sampling rate. An asserted time of the first phase signal and an asserted time of the second phase signal are separated by a predefined non-overlap time. The apparatus also includes a switched-capacitor circuit with a plurality of switched capacitors operably coupled to the first phase signal and the second phase signal. An amplifier is operably coupled to the switched-capacitor circuit and has a response time inversely proportional to an adaptive bias current. A bias generator is coupled to the amplifier and operates to modify the adaptive bias current responsive to the asserted time of the first phase signal.
