Abstract:The design of a 100 kHz frequency reference based on the electron mobility in a MOS transistor is presented. The proposed low-voltage low-power circuit requires no off-chip components, making it suitable for Wireless Sensor Networks (WSN) applications. After one-point calibration the spread of its output frequency is less than 1.1% (3¾) over the temperature range from -22 ±C to 85 ±C. Fabricated in a baseline 65-nm CMOS technology, the frequency reference occupies 0.11 mm2 and draws 34 ¹A from a 1.2-V supply at room temperature.
