Abstract

This paper investigates the impact of a GALS (Globally Asynchronous Locally Synchronous) based clock phase modulation on the conducted emission. Accordingly, a large design can be partitioned into small synchronous modules, and scheduled to operate at different phases of the clock signal. By this way, we can reduce the number of simultaneous switching inside the circuits. As a result, the conducted noise will be reduced. Particularly, to evaluate the impact of the clock phase modulation on the conducted noise emission, we design 4 noise generators, and schedule them to operate at 4 different phases of a clock signal. In our preliminary study, a reduction of 2.4dB in the conducted emission at the fundamental frequency is achieved. We can get more reduction of 8.1dB at the first harmonic component of 64MHz. All the experiments are carried out on a Xilinx Spartan-3.
