Abstract

An RF Voltage Controlled Oscillator (VCO) design having improved power suppl y noise immunity. More particularly, a VCO resonant circuit that provides a hi gh circuit Q, immunity to noise, and is tunable over multiple distinct bands. T he resonant circuit is implemented in conjunction with an integrated circuit oscillator that requires a tuned circuit to determine the frequency of operation. When the integrated circuit oscillator is used as a Local Oscillator (LO) within a wireless phone it is subjected to numerous sources of power supply noise. In a Code Division Multiple Access (CDMA) wireless phone system the power supply to portions of the RF transmit path are cycled on an d off depending on the transmitted data rate. The present invention provides a n oscillator with increased immunity to the noise induced on the power supply due to power supply cycling.
