Abstract
An integrated circuit is described herein. In accordance with one embodiment, the circuit includes a voltage controlled oscillator (VCO) that is configured to receive a tuning voltage at a tuning input and to provide an RF oscillator signal at an oscillator output. The circuit further includes a first and a second switchable resistor network. The first switchable resistor network includes at least a first resistor and at least a first switch and is connected between the tuning input of the VCO and a first node, which operably provides a first voltage. The second switchable resistor network includes at least a second resistor and at least a second switch and is connected between the tuning input of the VCO and a second node, which operably provides a second voltage. Furthermore, the circuit includes a control circuit that is configured to activate, dependent on a control signal, either the first switchable resistor network, the second switchable resistor network or both, the first and the second resistor networks.
