Abstract :
The output conductance of gallium arsenide MESFETs, traditionally considered detrimental to device performance, is exploited to effect the cancellation of distortion. This occurs in a common-source amplifier with correct loading and provides useful gain. A technique for characterising the device is presented to allow calculation of optimum load for minimum distortion.
