Abstract

Close
- Experimental data on analog performance of gate-all-around III-V vertical Tunnel Field-Effect Transistors (TFETs) and circuits are presented. The individual device shows a minimal subthreshold swing of 44 mV/dec and transconductance efficiency of 50 V−1 for current range of 9 nA/μm to 100 nA/μm and at a drain voltage of 100 mV. This TFET demonstrates translinearity between transconductance and drain current for over a decade of current, paving way for low power current-mode analog IC design. To explore this design principle, a current conveyor circuit is implemented, which exhibits large-signal voltage gain of 0.89 mV/mV, current gain of 1nA/nA and an operating frequency of 320 kHz. Furthermore, at higher drain bias of 500 mV, the device shows maximum transconductance of 72 μS/μm and maximum drain current of 26 μA/μm. The device, thereby, can be operated as a current mode device at lower bias voltage and as voltage mode device at higher bias voltage.
