摘要

A simple BiCMOS configuration employing the source-well tie PMOS-p-n pull-down combination is proposed for low-voltage, high-performance operations. The improved BiCMOS gate delay time over that of the NMOS-p-n (conventional) BiCMOS gate is confirmed by means of inverter simulations and measured ring oscillator data. The source-well tie PMOS-p-n BiCMOS gate outperforms its conventional BiCMOS counterpart in the low-voltage supply range, at both high and low temperatures. A critical speed path from the 68030 internal circuit is used as a benchmark for the proposed BiCMOS design technique. The measured propagation delay of the BiCMOS speed path is faster than its CMOS counterpart down to 2.3 V supply voltage at -10 degrees C and sub-2 V at 110 degrees C.
