This paper describes the theoretical analysis and experimental verification of voltage controlled oscillator (VCO) that overcomes the past attempts to combine wideband VCO and Phase-Locked-Loop (PLL) in one small package (0.6times0.6 inches) for configurable frequency synthesizer operations. Shrinking the size of planar resonator s has led to miniatur ized (0.3times0.3 inches) wideband VCOs that are the building blocks for tiny, high-per formance, PLL-based frequency synthesizers. The typical measured phase noise @ 10 kHz offset for 4950-5500 MHz synthesizer is -90 dBc/Hz with 5 V, 30 mA and settling time is less than 1 msec, and not limited to this frequency, and be extended from 100 MHz to 12 GHz.
