Abstract
Clock frequency-drift compensation is described for a clock generator. In an example, an oscillator circuit includes a clock generator configured to generate an output clock signal with a clock frequency, a first variable resistor coupled to the clock generator to vary the clock frequency, and a second variable resistor. A voltage divider has a reference resistor and the second variable resistor. The voltage divider is configured to generate a reference stress voltage between the reference resistor and the second variable resistor, and a correction feedback block is configured to compare the reference stress voltage to a reference voltage, to adjust a resistance of the first variable resistor, and to adjust a resistance of the second variable resistor in response to the comparing.
