Abstract
A fully differential amplifier having a start-up circuit is described. The fully differential amplifier may be a two-stage amplifier with a start-up circuit coupled between the stages. The start-up circuit may include a sense circuit coupled between a common mode input and internal nodes that are connect to output transistors of the fully differential amplifier. The sense circuit produces a reset signal that forces the fully differential amplifier into a mode of operation.
