The Class i output stage

In this article, Kendall presents a solid state unity-gain power output stage that has very low distortion and for which the biasing current can be set without the need for adjustments and without the need for thermal tracking or compensation techniques. The design is also very unsensitive to device parameters which gives predictable performance from a wide selection of power devices. Working in class AB, the crossover distortion is very low, even in open loop, making possible very linear open loop output stages.
