ABSTRACT:
Internal programmable voltage supply circuitry is provided for a programmable transistor integrated circuit device, such as a programmable logic device or a programmable memory device. The programmable voltage supply circuitry generates a programming voltage that is used to program the configuration of the programmable transistor device. The programmable voltage supply circuitry is calibrated by adjusting the programming voltage that is produced by the programming voltage supply circuitry to be approximately equal to an external reference voltage. The settings obtained during calibration are stored in a programmable memory on the programmable transistor device.
