ABSTRACT:
A voltage/current (V/I) source includes circuitry having first, second, third and fourth nodes, a first current source electrically connected to the first node, a second current source electrically connected to the second node, where the third and fourth nodes are between the first and second nodes, and an operational amplifier (op-amp) having an output, an inverting input, and a non-inverting input. The output is electrically connected to the third node, and the non-inverting input is electrically connected to a voltage source. A feedback line is between the fourth node and the inverting input.
