Abstract: | A novel BiCMOS full-swing circuit technique with superior performance over CMOS down to 1.5 V is proposed. A conventional noncomplementary BiCMOS process is used. The proposed pull-up configuration is based on a capacitively coupled feedback circuit. Several pull-down options were examined and compared, and the results are reported. Several cells were implemented using the novel circuit technique; simple buffers, logic gates, and master-slave latches. Their performance, regarding speed, area, and power, was compared to that of CMOS for different technologies and supply voltages. Both device and circuit simulations were used. A design procedure for the feedback circuit and the effects of scaling on that procedure were studied and reported |
