Abstract
A regulated cascode amplifier includes a main cascode amplifier and a feed-back amplifier. The main cascode amplifier has an input transistor coupled in a stack with an output transistor at an input control node. The feed-back amplifier including a plurality of transistors with gates of the transistors being coupled together to the input control node and with drains of the transistors being coupled together at a gate of the output transistor. The transistors of the feed-back amplifier are biased from connections to the main cascode amplifier for smaller chip area.
