A novel circuit technique is presented to prevent op-amps in switched-capacitor circuits from generating ‘spikes’ in the nonoverlapping period of clock phases. This technique is universal in that it is applicable to offset-compensated, parasiticand gain-insensitive amplifiers, integrators and sample/hold circuits. Experimental waveforms are also given to demonstrate its validity.
