Abstract
Low voltage current sources having a high effective output impedance over a wide voltage range, including when individual transistors exhibit low output impedance states at low voltages. The low voltage current source replicates its output current and compares the replicated current to the desired current. The error between the replicated current and the desired current is used as feedback to force the output current to equal the desired current.
