± 1.2V High frequency four quadrant current multiplier

A new high frequency four quadrant current multiplier is presented. The current multiplier uses complementary MOS devices in triode region and exploits the square-law behaviour of saturated MOS transistors. The circuit operates using the supply voltages of plusmn 1.2 V. The cutoff frequency is 1.74 GHz with a total harmonic distortion less than 0.065 % (at 1 MHz). The power dissipation is 1.2 mW.
