Abstract:
1. A voltage generator on an integrated circuit chip having an output voltage with a selectable digital temperature coefficient and digital level, comprising: a first input for a temperature coefficient code word, the temperature coefficient code word being bits representing digitally a given temperature coefficient among a predefined range of temperature coefficients of the output voltage; a second input for a voltage level code word, the voltage level code word being bits representing digitally a given voltage level among a predefined range of output voltage levels; a temperature sensor for sensing a temperature of the integrated circuit chip, said temperature producing a sensor voltage level to indicate a sensed temperature as a function of the sensor voltage level; an analog-to-digital converter for receiving the sensor voltage level to yield a temperature code word, the temperature code word being bits representing digitally the sensor voltage level among a predefined range of sensor voltage levels corresponding to a predefined range of temperature; a set of digital processing circuits for digitally computing an output voltage code word by inverting the temperature code word and forming a product with said temperature coefficient code word from said first input, and adding the product to said voltage level code word from said second input; and a digital-to-analog converter for converting the output voltage code word to a corresponding output voltage level.
