Abstract :
A new design for a first generation current conveyor implemented from complementary bipolar transistors is introduced. Its input cell consists of two translinear mixed loops in parallel. The circuit that acts in AB class can process currents with magnitudes greater than the bias current I0 and so generate very low harmonic distortion. It is characterized by low values for its parasitic input resistance and large -3 dB bandwidths. It can also be used with supply voltages as low as ±1.2 V
