For FE-SOI MOSFETs, the discharging time (ts), on resistance (Ron) of switch circuit, and output current (Iout) of current mirror show superior immunity to Nit and Lg variations compared to the SOI counterparts. FE-SOI MOSFETs show significant improvements in discharging time (-78% and -31%) at Vdd=0.4V and 1V compared to SOI MOSFETs due to the negative capacitance induced voltage amplification and higher drive current. Besides, FE-SOI switch circuit exhibits lower Ron and better Ron flatness which suppresses distortion for audio and signal processing applications. FE-SOI current mirror with larger output resistance shows better current matching (smaller Iout/Iref) than SOI one, and comparable mirroring performance compared to the stacked SOI current mirror. Therefore, FE-SOI current mirror can significantly reduce the circuit complexity and area penalty while maintaining adequate mirroring accuracy. ? 2019 JSAP. |
