CONSTANT-CURRENT SOURCE CIRCUIT
2.1 Basic Circuit Design The fundamental design of an AC constant current source often involves a combination of inductors, capacitors, and transistors. Inductors, due to their property of opposing changes in current, help in maintaining a relatively stable current flow. Capacitors, on the other ...
Conversely, a perfect constant current source/sink is an open circuit (infinite resistance) to AC, and even an infinite AC voltage across it is incapable of driving any AC current through it. Active constant current sources/sinks are becoming more common, but inductors were the traditional AC ...
