An MOS voltage boost circuit includes a first field-effect-transistor coupled between ground and an output node and a second, depletion type, field effect transistor coupled between the output node and a source of supply voltage (VDD). The first transistor is turned off by a disabling signal, and the second transistor is turned on by an enabling signal derived, in part, from the disabling signal. This produces a first voltage at the output node. A third field-effect-transistor is capacitively coupled between the output node and the enabling signal to boost the output voltage when the enabling signal terminates.
