Mixed-mode vs. Spectre• Schematic modified to emulate measurement setup- Include all parasitic elements (bias tees, cabling, scope, etc..)Transients at BGR outputTransients at oscilloscopeJohn D. Cressler, 5/25/10 40
Progress & PlansNo-cost Extension Granted to 8/31/10Continue Our Exploration of Device-level SiGe Hardening• Near-term broadbeam heavy ion experiment planned- Inverse-mode cascode shift registers- SiGe on SOI shift registers• Characterization of self-heating effects in SiGe on SOI - new Agilent pulse-mode measurement system will support this• Continue to investigate device-circuit interactions (mixed-signal)• Continue to hone TCAD for addressing circuit response Much Learned! ….. Much to be Done Still!Wish List – a follow-on MURI – hint, hint!John D. Cressler, 5/25/10 41
