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 application in wireless sensor networks (WSN). After a single-point calibration, the spread of its output frequency is less than 1.1% (3 ) over the temperature range from -22 C to 85 C. Fabricated in a baseline 65 nm CMOS technology, the frequency reference circuit occupies 0.11 mm.
