- Abstract
As the powerful competitor of the next generation clock cistribution technology, resonant clock scheme shows obvious advantages in low power consumption and low skew. But the application of this technology is United because of the absence of a systematic design methodology. To solve the problem, a physcal design method of bufferless resonant Clock Distribution Network (CDN) was proposed in this paper. The method uses the conventional synchronous design flow and implements resonant clock network efñcíently. Based on SPICE analysis and optimization for the design parameters of the resonant CDN, the proposed method makes the physcal design converge fast at the target frequency. A muitipiíer circuit was designed using this method, and the resuits of post--layout SPICE show that, compared wtth the synchronous design employing tree-based and mesh-based CDN, the buffer!ess resonant CDN based circuit can save CDN power up to 64, and total power up to 16,. Additionally, the clock skew in resonant CDN is less than 2% of clock cyde under different process corners.
