    In this paper the design and implementation of a delay-locked loop based temperature compensated MEMS clock is presented.
    The system is providing a temperature compensated 48 MHz clock signal for the range of - 40 to 85°C.
    The temperature compensation is achieved by a combination of initial and an autonomous background calibration.
    The main design guidelines have been on high integration level and minimum silicon area while maintaining a low timing jitter and power consumption.
    The design was implemented by utilizing Austria Micro Systems (AMS) 0.35 μm standard CMOS process technology.
    The implementation occupies 1.75 mm 2 of silicon area.
