High sensitivity and low power skin sensor implementation and performance comparison using CMOS and CNFET

Skin sensor is the most critical part for controlling robot sensing behavior. In this paper, we provide circuit implementation and simulation for sensing the pressure in the skin sensor using CMOS and CNFET at 32nm technology node. The proposed scheme can be used as an active matrix like memory element in the skin sensor and it is demonstrated by showing the output image according to the skin sensor´s pressure location using Matlab implementation. The circuits are compared with CMOS and CNFET (Carbon Nanotube FET) at different supply voltages to show the feasibility of the scheme. Also, low-leakage circuit technique is applied to the proposed sensing circuit.
