Abstract :
A switched-capacitor block is proposed. It uses single op-amp, two capacitors, and, through different feed-in branches, the block can be used as a delay, negative constant multiplier or a summer circuit. The proposed block is parasitic-free and requires a two-phase clock for its operation.
