Power efficiency and production cost are the very important design parameters of wireless communication with the growth of ubiquitous computing. Compressive sensing enables the receiver in such devices to sample below the Shannon-Nyquist sampling rate, which may lead to a decrease in the two design parameters. By using a digital self-calibration technique, the frequency of the Spread Spectrum Clock Generator (SSCG) has a triangular modulation profile and relaxes the process variations. The measured RMS and peak-to-peak jitters are 2.67ps and 19.90ps in a spread-spectrum modulation, respectively.
