Abstract
An integrated circuit device comprises tuning signal circuitry for generating a tuning signal for calibrating a voltage controlled oscillator (VCO). The tuning signal circuitry is arranged to receive a target voltage signal that is representative of a target voltage across at least one passive element within a resonant tank circuit of a VCO that is being calibrated, generate a VCO simulation signal representative of an average voltage difference across at least one active component of the VCO that is being calibrated, and output a tuning signal based at least partly on the received target voltage signal and the generated VCO simulation signal.
