Abstract
An apparatus, method and system are described for providing a low power replica biased regulated supply voltage without the size requirements of using a large resistor coupled between the source of a master transistor and ground. Instead, a source of a replica transistor diode may be biased with a bias voltage, and the gate and drain of the diode may be biased with a current bias. Additional descriptions provide the supply voltage without the size requirements of a resistor coupled between a source of one or more pass transistors and ground. Instead, the source of the pass transistor(s) may be biased with a 'leaker' current.
