Original Abstract Submitted
A Voltage-Controlled Oscillator (VCO) includes a cross-coupled transconductance cell. A transformer comprising a primary coil and at least one secondary coil, wherein the primary coil is connected to the cross-coupled transconductance cell. A primary coil varactor is connected to the cross-coupled transconductance cell in parallel to the primary coil. A variable inductive tuning component connected to the at least one secondary coil. A mode switch connected to the at least one secondary coil and configured to select a frequency mode of operation of the VCO by engaging or disengaging the variable inductive tuning component from operation with the primary coil varactor to generate oscillation at a center frequency of the VCO.
