Current Sources (and sinks)—understanding compliance range
Bruce Trump
We get many questions on our forums about designing current sources of all
types—constant currents, voltage-controlled currents, AC currents, high
currents, low currents, active current sources and passive current sinks.
All different kinds. A single blog can’t begin to cover all this ground. I
can, however, provide some basic background and links for more information.
A key point: A current source cannot force a current to flow into a load
without applying the necessary voltage. Think of a current source as a
circuit that adjusts its output voltage to cause the desired current to
flow in the load. You can’t make a 10mA current flow into a 1k-ohm load
without applying 10V. Or perhaps, mo
