Abstract: A broadband high output current output stage includes at least one first differential pair for enhancing the bandwidth. A second differential pair is further disposed in the circuit. The second differential pair is coupled to one of the first differential pair, such that a large output voltage swing is distributed to all transistors to avoid breakdowns thereof.

The first compensation unit compensates the electric characteristic of the high-frequency zero of the feedback unit and the bias unit, thereby broadening the linear bandwidth of the frequency response. The second compensation units are disposed between the first differential pairs. Each second compensation unit compensates the high-frequency zero of the node where each two first differential pairs are cascaded, thereby further broadening the linear bandwidth of the frequency response.
