Abstract

An NMOS Function Generator disclosed here has two control signals: X and Y. This circuit can be inserted into any data path to perform the following logic: Fig. 1 shows the circuit implementation using Differential Cascode Voltage Switch Scheme. Fig. 2 shows a single-ended alternative. In both Fig. 1 and Fig. 2, X and Y are control signals, I is the input line, and Q is the output line. The NMOS transistor 10 in Fig. 1 is a depletion-mode device and has a ratioed load. The NMOS transistors 12, 14 in Fig. 1 and transistors 16, 18 in Fig. 2 have ratioed loads.
