Hanumolu, Pavan Kumar Qian, Ducheng 2020-08-27T00:51:26Z 2020-08-27T00:51:26Z 2022-08-27T00:51:40Z 2020-05-11 2020-05 Highly stable clock reference is critical to many applications, including communication, timing, frequency synthesis, and synchronization. This thesis introduces a practice of utilizing a temperature sensor to compensate for an RC oscillator based on FLL (frequency-locked loop), on the same die of the temperature sensor, with the assistance of a frequency counter and a computer. The TCO (temperature-compensated oscillator) and the temperature sensor are presented by Khashaba et al. (2020). The additional digital circuitry for compensation can be further integrated on-chip. The achieved output frequency at 37.5 MHz varies by 875 ppm (parts per million) across the whole temperature range from -30 C to +80 C.
