About this document
Clock-Tree Driver Mixing for Noise Reduction by srinivas is a document available to read on EtoBox.
This document proposes a method to reduce power supply noise by mixing high threshold voltage (HVT) and weak low threshold voltage (LVT) clock drivers in a clock tree to spread out the switching of drivers while maintaining low skew at the sinks. A two-phase algorithm first constructs the clock tree with a mix of drivers and then performs a bottom-up delay correction to minimize skew. When implemented in a 40nm process, the method achieved a 35-70% reduction in clock tree peak current and similar reduction
