ABSTRACT:
A mechanism for discharging parasitic capacitance at an input of an operational amplifier, which is shared between two stages of a pipelined analog-to-digital converter and/or two channels of signal processing circuitry. The operational amplifier contains two input circuits that are time multiplexed in a manner that allows capacitance to be discharged at one input circuit while the other input circuit is inputting signals into the amplifier. The discharging of the parasitic capacitance substantially mitigates the memory effect and the problems associated with the memory effect.
