Voltage–controlled oscillator (VCO) is the generator that can be tuned over a wide range of frequencies by applying a control voltage to it. The device uses internal oscillation circuit and operates without external components. Frequency tuning range is defined by a control voltage of a build-in switched capacitor sections, and the built-in varicap is used for a fine adjustment.
The block is fabricated on SMIC CMOS 0.18 um technology.
