Abstract :
Measured and modelled results are compared for bipolar heterojunction transistors (BHJTs) and integrated circuits. We describe a CAD package for the design of BHJTs and we report measured ECL ring oscillator gate delays of 50 ps. Divide-by-four circuits operate up to 1.6 GHz compared with a predicted value of 1.5 GHz.
