Abstract :
A comprehensive analysis of operational tall triple-gate MuGFET ring oscillators (ROs) is presented for the first time. Device geometries, process options and best inverter layout are discussed based on measured power and delay. A MOS model 11 based macro-model has been calibrated and correlated to hardware to enable a study on work-function tuning, conformal S/D extensions, strain engineering, raised S/D extensions and their impact at circuit level. Performance is benchmarked against reference bulk-planar LSTP and HP CMOS processes options to determine MuGFETs applicability opportunities. Finally, a new metric is used to assess CMOS technologies circuit potential, demonstrating the superior characteristics of MuGFET devices for low-power (LP) and for low-operational power (LOP) applications
