 Abstract

A novel and useful wideband FM demodulator operating across an 8 GHz IF bandwidth for application in low-power, wideband heterodyne receivers. The demodulator includes an n-stage ring oscillator that is injection locked to a wideband input signal. Locking to the input frequency, it divides the FM deviation by n, thereby facilitating as well as reducing the energy required for wideband demodulation. The quadrature-phased output of the ring oscillator is auto correlated using a low-power folded CMOS mixer capable of detecting FM up to 400 Mb/s over a 2-10 GHz IF frequency range.
