ABSTRACT:
A CMOS decoder capable of providing a one of n, a two of n, or a three of n decoded output, where n is equal to the number of outputs of the decoder and is a function of the number of bits in a digital signal to be decoded. A first plurality of transistors are used to precharge each of the decoder's outputs to a first voltage potential. A second plurality of transistors are placed in series between the first node and each of the outputs. The second plurality of transistors are controlled by the coded digital signal that is being decoded. The number of decoded outputs can be varied by connecting some of the outputs to some of the transistors of the second plurality of transistors or by connecting others of the outputs to junctions formed by the series placed transistors. In a preferred embodiment, a pair of back-to-back inverters are connected to each of the outputs to provide a static decoder.
