6.3 Advanced current mirrors: wide-swing
www.d.umn.eduFolded-cascode OpAmp A differential-input single-ended output folded-cascode OpAmp is shown below. The current mirror in the output side is a wide-swing cascode one, which increases the gain. The basic idea of the FC-OpAmp is to apply cascode transistors to …
