Low Voltage Current Mode Instrumentation Amplifier

This paper present a Current Mode Instrumentation Amplifier (CMIA) that employs a low voltage Extra-X Current Conveyor (EX-CCII), operable at ±0.75V. The proposed circuit utilizes one EX-CCII, and a grounded resistor. The circuit provides the low input impedance of 105 Ω and high output impedance of 0.31 MΩ which is favourable for the cascading without additional buffers. The non-ideal and parasitic effects on the circuit performance are being carried out. The theoretical predictions are well supported through verification results by using the PSPICE program.
