Patent ID: 7265629

Claim:
A voltage generating circuit for providing an output voltage corresponding to an input voltage and at least one measurable parameter, comprising: a monitor circuit for sensing the at least one measurable parameter and for converting said at least one measurable parameter into an offset address having a first portion, a second portion and a third portion while the voltage generating circuit is inactive, the monitor circuit including a process parameter sensing circuit for measuring a threshold voltage of a minimum-sized transistor, a process A/D converter for receiving the measured threshold voltage and converting said measured threshold voltage into the first portion of the offset address, a voltage supply parameter sensing circuit for measuring a supply voltage coupled to the voltage generating circuit, a voltage supply A/D converter for receiving the measured supply voltage and converting said measured supply voltage into the second portion of the offset address, a temperature parameter sensing circuit for providing a voltage corresponding to a temperature, and, a temperature analog-to-digital converter for receiving the voltage and converting said voltage into the third portion of the offset address; and, a digital compensator circuit for receiving the input voltage and the offset address, the digital compensator circuit converting the input voltage into a base address and providing a data word addressable by a combination of the base address and the offset address, the digital compensator circuit including a D/A converter for converting the data word into the output voltage.
