摘要： A voltage-controlled oscillator (VCO) having an operating frequency dependent on a total capacitance of selectable tuning capacitors can be fabricated within an integrated circuit (IC). The VCO can include active electronic devices fabricated within a set of lower layers of the IC and selectable tuning capacitors having electrically conductive structures separated by dielectric material fabricated within a set of upper layers of the IC. The upper layers of the IC are located above the set of lower layers of the IC. The VCO can also include a set of interconnect structures configurable to select a total capacitance of the selectable tuning capacitors by electrically interconnecting the first portion of the VCO to capacitors of the at least one selectable tuning capacitor.
