Abstract: “This paper presents the pre and post layout simulation results for a pierce oscillator integrated with MEMS SAW resonator. The oscillator is designed to be interface with 1.78GHz MEMS SAW resonator. The pierce oscillator has achieved 18dB gain, 1.8GHz bandwidth and about 100o phase performance. The simulation is done using CMOS 0.35u technology. The pre layout simulation of MEMS oscillator is sustained at 1.775GHz, with 0.8V voltage swing. The post layout simulation is sustained at 1.766GHz and 0.35V voltage swing. The phase noise performance after post layout simulation is 97.94dBc/Hz at 100kHz cutoff frequency.”
