Abstract: Disclosed is a basic DCVS (differential cascode voltage switch) tree construct, which can be used as a uniform basis for constructing DCVS logic circuits, register-latch circuits and circuits which can be conditioned individually to function as either or both DCVS logic and register-latches. In addition to logic and load sections that may be identical to corresponding sections of prior art DCVS trees, this construct contains gating elements for providing unique functions of isolation, precharge support and latch input coupling. The isolation function is used to electrically isolate the logic and load sections from each other, so that each section can be made to operate in a mode which is independent of the other section. The precharge support function allows precharging of circuits in the logic section without involvement of the load section. The latch input coupling function allows signals to be applied to and latched in the load section from a source other than the respective logic section. Use of arrays of such trees for constructing complex logic circuits is described.
