Abstract

This paper presents an 8.2MHz relaxation oscillator with swing boosting and self threshold tracking, designed to improve both period jitter and frequency stability. A self-threshold-tracking loop ensures the switching threshold is kept in a constant, reducing the frequency uncertainty from process, temperature and supply voltage variations. Implemented in a 180nm CMOS process, the design achieves a period jitter of 7.66psrms, an Allan deviation floor of 1.56ppm, a temperature coefficient of 123ppm from -20 to 100°C, and an FOM of 160.9dBc/Hz while only consuming 46.3μW. The power efficiency of the design is 5.6kHz/nW.
