Abstract: A highly linear transconductance amplifier using source degeneration is provided to improve linearity by obtaining transconductance from a source degeneration differential amplifier. Loaders(514, 516) are composed of a first load terminal and a second load terminal having predetermined resistance. Main differential amplifiers(510,512) are connected between the loader and the voltage-dependent resistor, and the first input voltage and the second input voltage differentially are amplified and outputted. A bias current source(500) biases the main differential amplifier, and the source degeneration resistor and non- linear-resistors(506,508) are connected between the main differential amplifier and the bias current source.
