Sažetak

The purpose of this study is to present a new design for an electronically tunable instrumentation amplifier. The current-mode design approach is used for the proposed circuit. The proposed current-mode instrumentation amplifier employs a single Extra-X Current Controlled Current Conveyor (EX-CCCII) and a grounded resistor. This circuit design is very simple and suitable for IC integration. Because of the circuit's high output impedance, it can be cascaded with other current-mode circuits without the need for a buffer. In addition, this circuit is electronically tunable with the bias current from EX-CCCII. The proposed instrumentation amplifier provides good frequency performance with a wide bandwidth for differential gain and CMRR. The effects of non-idealities of EX-CCCII and its parasitic elements are also analysed. To validate the proposed instrumentation amplifier, various simulations are performed with the CADENCE VIRTUOSO SPECTRE simulator using 0.18 µm CMOS technology parameters.
