Abstract: An oscillator circuit includes transistors that are cross-coupled through routing conductors in a first conductive layer. The oscillator circuit also includes a varactor, a capacitor, and an option conductor in a second conductive layer. The option conductor forms at least a portion of a connection between one of the transistors and the capacitor or the varactor.

Abstract: A first capacitor has a capacitance adjustable to a set point value by application of a bias voltage. A second capacitor also has a capacitance adjustable to a set point value by application of a bias voltage. The first and second capacitors are arranged to receive the same bias voltage generated by a control circuit. The control circuit receiving the set point value as an input and generates that bias voltage in response to a quantity representative of a capacitance of the second capacitor.

Abstract: A frequency modulator includes a first pair of diodes with two capacity diodes, and a second pair of diodes with two additional capacity diodes. The second pair of diodes is employed in parallel. The frequency modulator also includes a first modulator input for reception of a first modulation signal and a second modulator input for reception of a symmetrical second modulation signal. Both pairs of diodes are coupled to an oscillator unit.

Abstract: A frequency calibration method for calibrating an output frequency of a voltage-controlled oscillator is provided. The voltage-controlled oscillator includes a first capacitor bank, a second capacitor bank, and a third capacitor bank. The first capacitor bank and the third capacitor bank are initially disabled and the second capacitor bank is initially enabled. The method includes, when the initial output frequency is lower than a reference frequency, adjusting the capacitance of the second capacitor bank until the calibrated output frequency is greater than the reference frequency, and when the initial output frequency is greater than the reference frequency, enabling the first capacitor bank and gradually increasing the capacitance of the first capacitor bank until the calibrated output frequency is lower than the reference frequency.
