Frequency Synthesis for a Low-Power 2.4 GHz Receiver Using a BAW Oscillator and a Relaxation Oscillator

In this paper, a solution to realize local oscillators (LO) for a low power super-heterodyne receiver is presented. The first oscillator uses a bulk acoustic wave (BAW) resonator with high Q-factor. A quasi- harmonic quadrature relaxation oscillator with large tuning range is used to compensate for variations in the first oscillator and to cover the entire bandwidth for multiple channel selection.
