using kirkoff laws with dependent current sources so I've uh got a large problem here it's actually so big that the circuit continues so this is sort of one circuit here and it's it is a monster I'll ...

An interesting analog design problem is the precision current source. Many good designs are available, but most are the three-wire types that can be used as a positive (see Figure 1) or a negative ...

It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...
