Devices exhibiting Negative Differential Resistance (NDR) in their I-V characteristic are attractive from the design point of view and circuits exploiting it have been reported showing advantages in terms of performance and/or cost. In particular, logic circuits based on the monostable to bistable operating principle can be built from the operation of two series connected NDR devices with a clocked bias. Monostable to Bistable Logic Element (MOBILE) gates allow compact implementation of complex logic function like threshold gates and are very suitable for the implementation of latch-free fine grained pipelines. This pipelining relies on the self-latching feature of MOBILE operation. Conventionally, MOBILE gates are operated in a gate level pipelined fashion using a four-phase overlapped clock scheme. However other simpler, and higher through-output interconnection schemes are possible. This paper describes latch-free MOBILE pipeline architectures with a single clock and with a two phase clock scheme which strongly rely on distinctive characteristics of the MOBILE operating principle. Both the proposed architectures are analyzed and experimentally validated. The fabricated circuits use a well-known transistor NDR circuit (MOS-NDR) and an efficient MOBILE gate topology built on its basis. Both solutions are compared and their distinctive characteristics with respect to domino based solutions are pointed out. |
