Abstract
A receiver includes a harmonic injection-locked oscillator, which receives an RF modulated signal and provides an output to two parallel signal paths. A fundamental injection-locked oscillator is provided on one of the signal paths. A phase discriminator detects a phase difference between signals that have passed through the first and second signal paths. At least one of the signal paths includes an amplitude limiting circuit. One or more of the signal paths may include an adjustable delay circuit.
