  • Abstract
    A CMOS high-linearity transconductor useful for IC filtering applications is presented. It is based on a feedback unity-gain amplifier driving a resistor to achieve linear voltage-to-current conversion. Simulation results are provided on a design example using a 0.35-mum technology, powered from a 3.3V supply, and using a total dc current of 150 muA. The 3-dB bandwidth was 630 MHz and HD3, onto a load resistor of 20kOmega, was -82 dB at 1MHz.
