Abstract
A transformer based voltage controlled oscillator (VCO) is provided with a primary resonant circuit having a first inductor connected in parallel with a variable first capacitance circuit. A secondary resonant circuit is formed from a second inductor connected in parallel with a variable second capacitance circuit, and also includes a mode control circuit. The mode control circuit controls the direction of current flow through the secondary resonant circuit inductor. The first and second inductors are inductively mutually coupled in either an even mode or an odd mode in response to the mode control circuit. The VCO supplies a first resonant frequency in response to even mode operation, or a second resonant frequency, greater than the first resonant frequency, responsive to odd mode operation. The VCO may include a first electrically tunable varactor shunted across the first capacitance circuit and a second electrically tunable varactor shunted across the second capacitance circuit.
