This paper discusses the design of a basic feedback oscillator, using a lumped element resonator with varactor control. A design center frequency of 1GHz has been chosen, with a tuning bandwidth of 50MHz (ie 10% or 5.5MHz/V) and a required phase noise performance of better than –70dBc/Hz at 10KHz offset.
