A novel instrumentation amplifier using only current controlled conveyors (CCCIIs) is
proposed. The new circuit with no resistors offers a wide bandwidth, a high CMRR,
electronically adjustable gain and a good dynamic range. The proposed circuit also
provides simultaneously a high impedance output current. The circuit is also analysed for
the non-idealities of conveyors. RSPICE simulation results are included to support the
proposed theory.
