Claim:
1. A system, comprising: a front end circuit configured to receive an input voltage and to provide a regulated front end direct current (DC) voltage; a multichannel source circuit coupled to the front-end circuit, the multichannel source circuit comprising a controller, a reference voltage circuit, and a plurality of source circuits, wherein each source circuit in the plurality of source circuits represents a distinct output channel, and wherein the multichannel source circuit is configured to generate a constant current output for each source circuit in the plurality of source circuits; and a plurality of loads, wherein each load in the plurality of loads is connected to a corresponding source circuit in the plurality of source circuits and is configured to receive the corresponding constant current output via the corresponding source circuit, wherein the controller is configured to generate an input to the reference voltage circuit, wherein the reference voltage circuit is configured to generate a reference voltage and to provide the reference voltage to the plurality of source circuits, and wherein the reference voltage is based upon the generated input.
