ABSTRACT:
In response to complementary clock signals provided from a driver, a charge pump operates to provide an output voltage which is a down-converted negative voltage. The voltage between this output voltage and a predetermined positive reference voltage is capacitance-divided by capacitors. The capacitance-divided positive voltage is applied to a comparator, whereby a reference voltage is compared with the above positive voltage. An output signal of the comparator is applied to the driver. In response, the driver controls the operation of the charge pump, whereby the output voltage is clamped at a predetermined voltage level for output.
