ABSTRACT:
A trimmable circuit includes a first transistor for generating an output current and a plurality of programmable trimming networks connected to the first transistor for regulating the output current of the first transistor. The plurality of programmable trimming networks include a network for decreasing the output current of the first transistor by introducing a second transistor into the trimmable circuit to draw current away from the first transistor and a network for increasing the output current of the first transistor. The trimmable circuit further includes a voltage-divider circuit connected to the plurality of programmable trimming networks, for limiting the voltage across any trimming network during programming.
