Abstract
A spread-spectrum clock generator is implemented using a nested modulation profile to reduce the peak power levels of radiated electro-magnetic emissions in display products. The display data interface is a potential source of interference, and the spread spectrum technique has been extensively used for display interfaces. The proposed nested profile can further reduce EMI without any degradation in the other characteristics. A test chip was fabricated using a 55nm CMOS process, and the test results indicate a 41dB reduction. The sensitivity of a wireless receiver to interference is tested, and the EVM results for the proposed nested profile exhibits an improvement of 1.4dB compared to those of the triangular profile.
