Abstract

Clock synchronization Performance measurement Silicon Topology Traveling waves
Conference Title: 2022 IEEE International Symposium on Circuits and Systems (ISCAS) Conference Start Date: 2022, May 27 Conference End Date: 2022, June 1 Conference Location: Austin, TX, USARotary traveling wave oscillators (RTWO) are designed to provide a high frequency clock signal through the silicon interposer to multiple chiplets in a heterogeneous 2.5D system. In particular, two different RTWO synchronization topologies are presented: 1) Active interposer RTWO and 2) passive interposer RTWO. The proposed topologies are evaluated across a silicon interposer with a dimension of 42 mm × 20 mm. Each topology is implemented with post-layout, parasitic extracted models for a clock frequency of ≈8 GHz. The performance metrics are presented for clock period, skew, rise time, fall time, and oscillation start-up and settling times across the multi-die system (MDS) with SPICE based simulations.
