Abstract:
A DC voltage generator system for an integrated circuit, said generator system being operated by a supply voltage at or near one-volt and comprising:a negative voltage pump circuit comprising: first means for receiving a clock signal and alternatively outputting a high portion of said clock signal from a first pair of outputs; first means for switching between one of two inputs for alternatively receiving said high portion of said clock signal from said first pair of outputs and outputting an intermediate voltage and a first logic high output from one of two outputs, where each of said one of two inputs includes a switch connected in series with an inverter; second means for alternatively receiving said logic high output from said one of two outputs and outputting a second logic high output from a second pair of outputs; and second means for switching between one of two inputs for alternatively receiving said second logic high output from said second pair of outputs and outputting a negative output voltage.
