Current-mode feedback source follower with enhanced linearity

Abstract:

An example apparatus includes a first transistor coupled between a supply node and a first node, a current mirror having a first side and a second side, and a second transistor coupled between the first node and the first side of the current mirror. The input buffer further includes a third transistor coupled between the first node and the second side of the current mirror, and a first capacitor coupled between a source and a drain of the second transistor.
