Abstract :
Presents the performance of DTCSO (digitally temperature-compensated SAW oscillator) using PLIC (polylithic integrated circuit) technology on quartz-on-silicon wafer. A prototype DTCSO reference oscillator is designed and fabricated on a QoS wafer and shows the phase noise performance -115 dBc/Hz at 10 kHz offset, 7.5 mW power consumption. The frequency stability performance of 4.5 ppm is very comparable with that of bulk crystal TCXO, demonstrating the feasibility of integration of reference oscillator for high performance true single chip radio
