Compound triple cascoded mirror

机译:复合三级联镜

摘要

A triple cascoded mirror active load includes three transistors (20), (26) and (28) in a first leg and three transistors (22), (30) and (34) in an output leg connected to an output node (18). The first leg receives a current on an input node (14) on the drain of transistor (20). Transistor (20) has the gate thereof connected to the drain of transistor (26) with the gates of transistors (24) and (30) connected together and to a bias voltage. Transistor (20) is mirrored to transistor (22) by connecting the gates thereof together. Similarly, the gates of transistors (28) and (34) are connected together and also to the node (14). In this manner, the node (14) receives a low impedance on the input thereto, whereas the gate of transistor (22) sees a high impedance thereto and with only two transistors, transistors 26 and 28, disposed in a loop as a ratioed cascoded configuration.
