Description
Sensor interface has been widely used in applications areas such as pharmacy, food-processing, biotechnology, industries, and laboratories etc. The differential voltage current conveyor (DVCC) is a very versatile active building block and attained specialinterest for current-mode circuits. This paper attempts to explore an application of CNFET-based current conveyor (DVCC) for the design of a resistive sensor interface. The proposed interface circuit reduces 16.6% power than existing work. The design also minimizes the number of active and passive components in the circuit. Further, a DVCC based Instrumentation amplifier is presented which is also utilized for the simpler design of sensor interface. HSPICE simulations with 32 nm CNFET model are performed to test the design.
