A swing restored pass-transistor logic-based multiply and accumulate circuit for multimedia applications

Abstract

Swing restored pass-transistor logic (SRPL), a high-speed, low-power logic circuit technique for VLSI applications, is described. By the use of a pass-transistor network to perform logic evaluation and a latch-type swing restoring circuit to drive gate outputs, this technique renders highly competitive circuit performance. An SRPL based multiply and accumulate circuit for multimedia applications is implemented in double metal 0.4 /spl mu/m CMOS technology.
