Abstract
The present invention consists of a subcircuit which may be employed in integrated circuit technology to provide the necessary drop from a relatively high voltage source and to provide base current for biasing of associated transistorized circuitry. Each subcircuit employs four transistors and one resistor and provides an effective drop from approximately 1.1 volts when it is desired to provide at least 2 microamps of bias circuit. Additional subcircuits of similar configuration can be placed in series with the present circuitry to increase the amount of voltage drop in accordance with the requirements of the associated circuitry.
