摘要：An M-bit binary counter is disclosed having M sequentially ascending binaryvalue stages, the first stage being the lowest significant bit. Each stage above the leastsignificant bit stage has a subsequent value decoder (100) which has the function ofdetermining the effect of lower order carry bits on higher order stages with a minimumof signal delay. The decoder includes the feature of using natural threshold FET devicesin a transfer gate configuration to perform logical AND functions so as to minimize gatedelays in decoding a carry condition for higher order stages. A selective upcounting ordown- counting function is also disclosed.
