Abstract :
An analytical model for calculating propagation delay time of two-level series-gated CML high-speed bipolar circuits is presented. The analytical delay model accounts for different transistor sizes at the two levels. Moreover, high-current effects are also considered in the developed model. Exploiting these two features, the model has been successfully applied in optimizing the design of a variety of two-level series-gated CML circuits. A comparison with the results obtained by SPICE is presented to verify the applicability of the proposed model
