ABSTRACT:
A precision tunable VCO includes a bias transistor, a first inductor, a second inductor, a first input transistor, a second input transistor, a first capacitor, a second capacitor, a first precision tune capacitor circuit, and a second precision tune capacitor circuit. The bias transistor, the first and second inductors, the first and second input transistors, and the first and second capacitors are operably coupled to produce a differential output oscillation. The first precision tune capacitor circuit is operably coupled to the first leg of the differential output oscillation, wherein the first precision tune capacitor circuit provides a first precision capacitance value based on a calibration signal. The second precision tune capacitor circuit is operably coupled to the second leg of the differential output oscillation, wherein the second precision tune capacitor circuit provides a second precision capacitance value based on the calibration signal, wherein the control voltage, the first precision capacitance value, the second precision capacitance value, the first capacitor, the second capacitor, the first inductor, and the second inductor establish frequency of the differential output oscillation.
