A pseudo true single phase clock latch (pseudo "TSPC" latch) includes additional circuitry coupled to three previously floating nodes that can lose data depending upon the amount of leakage current associated with these nodes. The additional circuitry, including a positive feedback circuit, improves the performance of a true single phase clock latch circuit at lower frequencies without significant degradation in high frequency operation of the latch.
