Abstract
An integrated circuit has an internal supply voltage with a positive temperature coefficient, as a result of which the switching rate and the degree of 'hot carrier stress' are less sensitive to temperature. By using a reference voltage source having positive temperature coefficient, the normal effects of increasing temperature on switching rate and 'hot carrier stress' are compensated for, thus stabilizing circuit operation as a function of temperature. The reference voltage source is incorporated within a voltage converter which is already present in the circuit, to achieve a compact and efficient configuration.
