Reliable and Efficient Logic Circuit Design Using Pocket-Engineered NCFET
摘要
This work reports the characteristics of highly doped double pocket double gate NCFET (HDDP-DG-NCFET) based digital inverter under temperature deviation and the existence and non-existence of trap charges. Various concentrations of Gaussian and Uniform distribution of trap charges (1 × 1012—1 × 1014/cm3) have been considered. In addition, propagation delays have been calculated, and it is witnessed that the transient characteristics show the presence of undershoot in existence of interface trap charges. Furthermore, it is noticed that average propagation delays (tp) are 3 ps and 16.5 ps (6.5 ps) in the non-existence and existence of Gaussian (Uniform) interface trap charges, respectively. Moreover, a study of the impact of temperature (200 K-500 K) on circuit performance has been carried out, which shows that the average delay of the inverter increases as the temperature rises from room temperature. In addition, the study investigates the transient characteristics of inverter in the existence of several trap charges at numerous temperatures. Lastly, a comparative investigation of the propagation delays of the digital inverter based on HDDP-DG-NCFET with the existing designs has been performed.
