A Temperature-insensitive Current-mode Multiplier/Divider Using Only Double-output VDTA

This paper presents analog current-mode four-quadrant multiplier/two-quadrant divider based on only double output voltage differencing transconductance amplifier (DO-VDTA), without any external passive element. The proposed circuit is ideally temperature-insensitive. The PSpice simulation program is used to investigate the performance of circuit. The given results agree well with the theoretical anticipation. The power consumption is approximately 2.21mW at ±1.5 V power supply voltages.
