摘要

基于电流域大信号等效电路，提出了一种新的双极非阈值逻辑电路物理时序模型。通过与SPICE仿真结果的广泛比较，发现在不同的工作电流、电容负载、器件参数和输入激励波形与特征波形偏差不大的情况下，NTL逆变器的最大误差为25%。此外，计算过程中所消耗的CPU时间和内存比完全瞬态模拟时要少得多。

A new physical timing model for bipolar NTL circuits

Based on current-domain large-signal equivalent circuits, a new physical timing model for bipolar nonthreshold logic (NTL) circuits is developed. Through extensive comparisons with SPICE simulation results, it is found that the maximum error is 25% for the NTL inverters with different operating currents, capacitance loads, device parameters, and input excitation waveforms not deviating much from characteristic waveforms. Moreover, the consumed CPU time and memory in calculations are much less than those in full transient simulations.<>
