ABSTRACT:
An integrated circuit which provides multiple independently accessible low-on-state-resistance switches, using conventional CMOS technology. Charge pumping is used to boost the gate voltage to lower the on-state resistance. The surface of the chip consists primarily of a few very large path transistors. This chip is perferably combined with a power management chip which provides logic outputs, and the large PMOS switches are used for controlling the power supply to various other chips, such as SRAMs.
