Abstract
Apparatus adjusts the low supply voltage applied to the bipolar gate array circuits of a semiconductor chip to provide uniform propagation delay in the signals operated on by the array circuits notwithstanding variations in manufacturing tolerances and temperature variations. The apparatus includes a voltage regulator circuit and a first resistor located off the chip connected between its output and adjustment terminals and a second resistor located on the chip connected to the adjustment terminal of the regulator circuit. The voltage regulator circuit in response to changes in the resistance of the second resistor adjusts the low supply voltage at its output terminal so as to provide uniform signal delays through the array circuits.
