Impact of non-uniformly doped double-gate junctionless transistor on the performance of 6T-SRAM bitcell

This work substantiates the impact of Gaussian doping on the electrical performance of double gate junctionless field-effect transistor (DG-JLFET). To get a better understanding of the influence of non-uniform doping, the device is compared with uniform-doped DG-JLFET with various concentrations. The device is later used to demonstrate its usability in six-transistor static random access memory (6T SRAM) bitcell by studying the performance metrics, i.e. stability noise margin and write delay. A comparison of performance metrics is also given with uniformly doped DG-JLFET-based-6T SRAM. Improvement in static noise margin was observed with Gaussian doping without compromising with write access time.
