SSCG with Hershey-Kiss modulation profile using Dual Sigma-Delta modulators

This letter describes a spread spectrum clock generator (SSCG) circuit with the Hershey-Kiss modulation profile using two stacked sigma-delta modulators. The proposed Hershey-Kiss profile modulator generates various slopes to achieve non-linear modulation profile. Since the modulators are implemented by digital blocks, it can be modified for other applications. Simulation results show that peak power reduction level of 10.2dBm with 5000ppm down spreading at the 340MHz operation using 0.13m CMOS.
