Abstract

A current mirror for use with a transconductor is disclosed. The current mirror includes an input resistor which changes an input current to a voltage, an output resistor having a value which is scaled with respect to the input resistor, an amplifier which senses the input voltage and the voltage across the output resistor and an output transistor having a gate coupled to the output of the amplifier and a source coupled to the output resistor is disclosed. Such a current mirror advantageously provides a transconductor having low distortion.
