Abstract

This paper reports progress on directly mounting a quartz crystal on a CMOS oscillator and PLL chip. This approach minimizes the distance between the quartz crystal resonator and the oscillator circuitry and can allow reduced power with reduced stray coupling effects. This approach also allows simplified packaging and can reduce the volume and weight of precision oscillators.
