ABSTRACT:
A CMOS circuit which can act as a current regulator for a variety of general MOS circuits. The circuit has current-biasing network connected to the source electrode of a first transistor. The drain electrode of the first transistor is connected to an input terminal of a current mirror arrangement. The output terminal of the current mirror is connected to the drain electrode of a first diode-configured transistor. The source electrode of the first diode-configured transistor is connected to a second diode-configured transistor. By connecting output terminals at various nodes of the circuit, the current of a variety of MOS circuits may be regulated by the current-biasing network.
