Abstract
A circuit is provided for both boosting output current and providing short circuit protection in an integrated circuit such as an operational amplifier. In an embodiment, a current-boosting output stage with short-circuit protection includes six current sources and six transistors, where the the boosting of output current is achieved using positive feedback and the short circuit protection is achieved using negative feedback.
