摘要：

结合电流模逻辑(currentmode logic, CML)电路的高速低摆幅、抗干扰能力强、适合在高频下工作的优点以及BiCMOS电路高速大驱动的优点,设计了一种结构简单的基于BiCMOS的高性能CML三值D型触发器。采用TSMC 180nm工艺,使用HSPICE进行模拟。结果表明,所设计的触发器不仅具有正确的逻辑功能,且结构简单,与目前先进的三值D型触发器相比,平均D-Q延时降低95.6％～98.4％,PDP降低16.2％～96.8％,同时工作频率可高达15GHz,适合高速和高工作频率的应用。

Abstract:

A simple-structure high-performance CML ternary D flip-flop based on BiCMOS was proposed, which combined both advantages of BiCMOS and CML circuits, and included high-speed and strong drive ability of BiCMOS circuits and high speed low swing and low noise of CML circuits. Using TSMC 180nm process, the results of simulations carried out by HSPICE illustrated that the proposed circuit could not only have correct logic function, but also gain improvements of 95.6％-98.4％ in average D-Q delay and 16.2％-96.8％ in PDP compared with the advanced ternary D flip-flops. Furthermore, the work frequency could perform up to 15GHz. All of the results proved that the proposed circuit was suitable for high-speed and high-frequency applications.

Key words: flip-flop, multi-valued logic, current-mode logic, CML, low-power, high-speed integrated circuits
