LOGIC BINARY CIRCUIT

摘要

A logic inverter or NOR circuit exhibits push-pull output characteristics by employing a saturated (T3) feedback technique. This approach allows for emitter follower like up level drive (by T2) and transient low impedance down level drive (through T1 and T3). The disclosed saturated feedback technique improves capacitive drive capability, reduces both load and circuit delay and reduces circuit power dissipation.
