A low-voltage conveyor-based CMOS transconductor

This paper presents a linear CMOS transconductor utilizing two triode-biased MOS transistors as input devices. Linearity of the transconductor is achieved by fixing the drain-to-source voltages of the triode-biased transistors by use of two first-generation current conveyors (CCI). The proposed transconductor operates with a single supply voltage of 1.5 V and has an input voltage range of up to 1.5 V peak to-peak with transconductance of about 20 /spl mu/A/V within 1% THD.
