Abstract
A two input nonsaturating bipolar logic gate consists of just two bipolar transistors plus a pair of resistors plus two voltage buses. One resistor has a resistance R.sub.C and it is connected from one of the voltage buses to the collector of both transistors. The second resistor has a resistance R.sub.E and it is connected from the other voltage bus to the emitter of both transistors. Those resistances R.sub.C and R.sub.E are selected such that R.sub.C /R.sub.E >1 and 0.1<(V.sub.CC -V.sub.BE)R.sub.C /R.sub.E <0.8 V.sub.BE where V.sub.BE is the base to emitter voltage at which each transistor turns on and V.sub.CC is the voltage between the two voltage buses.
