Abstract :
A four-quadrant class AB CMOS current-multiplier is presented. Wide input range, high dynamic range, high cutoff frequency, good linearity and low consumption are the features of the technique. A nonlinearity error of 1.1% with a small-signal bandwidth of 66 MHz for a quiescent current of 25 μA and a supply voltage of 3.3 V in a 0.5 μm technology are obtained
