ABSTRACT:
The effect of supply voltage variations on an oscillator circuit output are compensated for to reduce supply pushing. The change in a value of a first capacitance in a first direction in response to the variation in the supply voltage is canceled using one or more diodes having a capacitance that changes in a second direction, opposite the first direction, in response to the variation in the supply voltage.
