This paper presents a MEMS-based real time clock with a temperature compensation system. The implemented circuit achieves a timekeeping accuracy of +/- 4 ppm over -40 degrees C ... 85 degrees C temperature range. It is built using a 27 kHz silicon resonator, differential PTAT temperature sensor with a 2nd order Sigma Delta ADC, and a DSP block for temperature frequency compensation. The circuit is powered by a 1.8V supply and draws 2 mu A current. The system has been implemented using a 0.18 mu m CMOS process.
