NEGATIVE SUPPLY VOLTAGE GENERATING CIRCUIT AND SEMICONDUCTOR INTEGRATED CIRCUIT HAVING THE SAME |
摘要 |
A negative supply voltage generating circuit includes a pulse generating circuit and a charge pump. The pulse generating circuit generates a first pulse signal and a second pulse signal in response to a clock signal. The first and second pulse signals have pulse widths different from each other. The charge pump generates a negative supply voltage by performing a charge pumping operation in response to the first and second pulse signals, and has a time interval between a switch-on time duration for charging a flying capacitor and a switch-on time duration for transmitting charges to an output capacitor.
