This paper presents a miniature timing microsystem based on a pair of co-integrated low and high frequency silicon resonators -430kHz or 522kHz and 26MHz respectively-so as to implement a W-level accurate, low power, temperature-compensated real time clock (RTC) and to generate low noise, low jitter clocks at any frequency between 1-50MHz in a reconfigurable way at less than 10mW power dissipation.
