ABSTRACT:
A regulator for regulating the output from a high-voltage pump, Vpump, to provide a regulated load voltage, Vpp, to a load in MOSFET integrated circuits. The regulator includes a MOSFET switch which when enabled in a first state connects Vpp to the integrated circuit voltage level, Vcc, and which when disabled in a second state allows Vpp to be driven to levels greater than Vcc. The regulator includes a multipath control circuit for controlling the switch state and for controlling Vpp. A first current path, Iramp, controls the rise-time parameters of Vpp and a second current path, Idis, controls the fall-time parameters of Vpp. The rise-time parameters and the fall-time parameters are separately controlled.
