Circuit for providing on-chip DC power supply in an integrated circuit

摘要

An on-chip DC power supply uses at least one series pass element which conducts responsive to a gating signal obtained by clamping an input potential to a preselected polarity and amplitude. A charge storage element serves to maintain an output voltage which is clamped to a predetermined maximum value. An output regulator provides a substantially constant second output voltage at a magnitude less than the output voltage set by the output clamping means.
