Patent JP-H0934572-A (JP)
Title: Power circuit
Inventor: KUDO RYOTARO
IPC: G05F3/24
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To decrease the number of circuit elements and also to extremely reduce the power consumption of a power circuit by providing both enhancement and depletion type MOS transistors TR and taking the output voltage out of a buffer circuit which outputs the voltage generated at the drain side of the depletion type MOS TR after the inverse amplification of the voltage. SOLUTION: An enhancement type MOS TR M1 has its drain connected to the current input terminal of a current mirror circuit 22 and its source connected to the reference potential. A depression type MOS TR M2 has its drain connected to the current output terminal of the circuit 22 and its source connected to the reference potential respectively. An error amplifier having the input offset voltage of a fixed level consists of both TR M1 and M2, and a negative feedback loop of the output voltage is formed by means of the error amplifier. In such a constitution, the leakage current flowing between a semiconductor substrate and a source electrode is immediately bypassed via the source electrode. Thus the current consumption can be extremely reduced.
