ABSTRACT:
The disclosure relates to a logic circuit wherein the voltage regulators of the ECL circuits, which use resistor ratios, the values of which are difficult to control in the formation of semiconductor circuits, are replaced by a series of diodes, the areas of which are very easy to control in semiconductor fabrication, to set the threshold voltages for the transistors. Diode voltage ratios are very controllable since the diodes change only about 18 millivolts for every factor of two in current change. Thresholds can therefore easily be set in five and ten millivolt increments, this being the procedure utilized herein. Embodiments are disclosed using the basic circuit in a stacked configuration to provide AND/NAND operation in addition to the OR/NOR operation of the basic embodiment.
