Abstract

A quasi-constant-sensitivity voltage-controlled oscillator ( VCO) using an offset-tuning junction varactor array is demonstrated with low standard deviation of 4.5 MHz/V and average sensitivity of 41 MHz/V. The varactor array utilizing PN-junction varactors provides high-linear capacitor-voltage response and low sensitivity variation. The VCO has a figure-of-merit (FOM) value, FOM_Kvco' of 0.11 and phase noise of -120 dBc/Hz at 1-MHz offset.
