Abstract
An improved high speed gallium arsenide (GaAs) to emitter coupled logic (ECL) voltage level converter is provided which consumes less power and also provides an improved speed-power product performance characteristic. The converter includes a three branch output circuit which emulates the operation of an ECL output driver. The emulator circuit causes faster switching by compensating for parasitic resistances and capacitance and is also provided with a gate discharge network which reduces switching time of the ECL output emulator.
