Oscillator system, method of providing a resonating signal and a communications system employing the same

摘要

An n^th-order oscillator system for providing a resonating signal, a method of generating a resonating signal and a communications system. In one embodiment, the n^th-order oscillator system, n being greater than two, includes (1) an amplifier configured to provide an intermediate signal and (2) a feedback loop including an n^th-order complex LC tank and configured to generate the resonating signal by feeding back a complex-filtered form of the intermediate signal to the amplifier.
