Original Abstract

In this paper, a novel low-voltage ultra-low-power class AB current conveyor of the second generation based on folded cascode operational transconductance amplifier OTA with floating-gate differential pairs is presented. The main features of the proposed conveyor are design simplicity and rail-to-rail input voltage range at a low supply voltage of +-0.5 V. The proposed conveyor has a reduced power consumption of only 10 uW. Thanks to these features, the proposed conveyor could be successfully employed in a wide range of low-voltage low-power analog signal processing applications. PSpice simulation results using the 0.18 um CMOS technology from TSMC are included to prove the results. As an example of application, a current-mode quadrature oscillator is designed and its functionality is proved by simulation.
