Clock Gating and Multi-Bit Register Clustering for Low-Power Design
Clock networks consume up to 40% of an ASIC’s dynamic power budget. Clock gating is the most effective logical optimization technique to minimize dynamic power by shutting down clock branches when registers are idle. Gating Logic Setup Time and Local Clock Skew Inserting Clock Gating Cells (ICGs) can introduce set-up timing violations on the gating […]

ESD Protection Circuit Design for Sub-5nm High-Speed Interfaces
At sub-5nm FinFET nodes, extremely thin gate oxides are highly vulnerable to dielectric breakdown. Designing robust Electrostatic Discharge (ESD) protection circuits for high-speed I/O interfaces requires protecting internal gates without degrading signal integrity. Parasitic Capacitance and ESD Window Narrowing Traditional ESD protection structures introduce parasitic capacitance that acts as a low-pass filter, attenuating multi-GHz high-speed […]
