Abstract:
A circuit which provides voltage regulation comprising:a charge pump which drives the voltage to be regulated, a PN diode whose N side is connected to the charge pump, diode connected NMOS field effect transistors connected in series to each other, the first of which is connected to the P side of said PN diode, a single or several intrinsic NMOS field effect transistors connected to the last of said diode connected field effect transistors, a current mirror discharge NMOS field effect transistor whose drain is connected to the source of said intrinsic NMOS field effect transistors and whose source is connected to ground, a diode connected NMOS field effect transistor current mirror whose source is connected to ground and, a current source which drives said the drain of said diode connected NMOS field effect transistor.
