Abstract :
Based on a previously reported low voltage class-AB CMOS linear transconductor, we propose a simple technique to modify such a circuit so that its transconductance gain is linearly dependent on external voltage. The applicability of the resulting transconductor in low voltage low power four quadrant analog multiplication is then presented. PSPICE simulation results of both the proposed transconductor and multiplier are given
