Demonstration of a Differential Layout Solution for Improved ASET Tolerance in CMOS A/MS Circuits

Layout techniques that exploit charge-sharing phenomena for analog single-event transient (ASET) mitigation in fully-differential analog/mixed-signal (A/MS) designs are experimentally explored in a 65 nm CMOS process. Benefits of the proposed RHBD layout techniques are illustrated through circuit simulations. Preliminary RHBD layout guidelines are discussed.
