Abstract :
This paper investigates the potential of self-timed property of differential cascode voltage switch logic (DCVSL) circuits, and examines architectural techniques for achieving self-timing in DCVSL circuits. As a result, a fast and robust handshake scheme for dynamic asynchronous circuit design is proposed. It is novel and more general than other similar schemes. The proposed self-timed datapath scheme is verified by an 8-bit divider which is implemented using AMS 0.6-μm CMOS technology, and the chip size is about 1.66 mm×1.70 mm. The chip testing results show that the divider functions correctly and the latency for 8-bit quotient-digit generation is 17 ns (about 58.8 MHz)
