Abstract :
UWB backscatter RFID systems require high quality clock signals and crystal oscillator is one of the few candidates. A study of a low-power parallel-mode crystal oscillator for such applications is presented. A 7.8125 MHz Pierce crystal oscillator is realized in a TSMC 90 nm CMOS process. It has a frequency stability of ±7 ppm from 0 to 70°C and draws 36 μW from a 1.2 V supply. The core area excluding pads is 0.021 mm2.
