<p>A self-adjusting voltage regulator circuit of a CMOS chip, for use with CMOS digital and/or analog circuit, providing a voltage which is selected in accordance with the characteristics of the chip to optimally current control operation of CMOS circuits on this chip. The voltage regulator circuit has a reference CMOS pair (61, 62) with a predetermined geometry, and current means (52, 66) are provided for driving a current through said reference pair which is adjusted to operate the pair at a desired point of current controlled operation. The voltage across the reference pair is utilized to provide the regulated voltage to other CMOS pairs (58, 59), which pairs have respective geometries of predetermined relation to the reference pair geometry, whereby the regulated voltage and the relative geometry provide current controlled operation of each such CMOS pair.</p> |
