Using device characteristics to obtain a low-power temperature-insensitive oscillator for smart dust networks

The paper shows how to take advantage of device temperature operating characteristics to obtain a temperature sensor, and use it to help generate a low-power temperature-insensitive oscillator. The oscillator serves as a carrier frequency generation circuit in an on-off-keying (OOK) transceiver system. We have described a low power temperature insensitive oscillator for radio frequency wireless communication. We have also presented a chip layout in a commercially available 0.13mum CMOS technology. The area of the temperature insensitive oscillator is 0.002mm².
