Switched capacitor array (SCA) circuits allow a fast acquisition of short signals as samples in memory cells, being an alternative to conventional converter circuits. Each memory cell of an SCA has a readout buffer circuit needed only during a short time, thus wasting power when is left ON. Presented is the design of a power cycling circuit that greatly reduces power consumption of SCA circuits by turning buffers ON only when needed. Results from circuit simulations of a prototype implementation are presented. The reduction on power consumption of SCA circuits with power cycling are computed from the results and compared to conventional circuits.
