Abstract :
To improve the density of BiCMOS sea-of-gates, bipolar and PMOS transistors are merged to form compact basic cells combined with the gate isolation technique. This structure occupies only 12% of the conventional bipolar transistor area. The density of the basic cell increases by 60% compared with conventional cells. The pull-up BiCMOS circuit achieves the fastest gate delay of 200 ps. A 16-bit multiplier in the test chip fabricated with 0.8 μm BiCMOS technology operates at 18 ns delay time
