Claim:
1. A voltage controlled oscillator arrangement comprising: a voltage controlled oscillator having an output and a tuning port, wherein the output provides an output signal at an operating frequency, the tuning port is configured to select the operating frequency of the output signal according to an applied voltage, the voltage controlled oscillator is supplied by a supply voltage, wherein the supply voltage is OFF during inactive portions of a cycle and the supply voltage is ON during active portions of the cycle; a bypass component configured to apply a bypass compensating signal to the tuning port during the active portions of the cycle and the bypass component is configured to be charged during the inactive portions of the cycle, wherein the bypass compensating signal compensates for an oscillator temperature of the voltage controlled oscillator; and wherein the bypass component is configured to have a positive to ambient temperature (PTAT) compensation applied only during the inactive portions of the cycle for the supply voltage of the voltage controlled oscillator.
