Abstract
A system and method according to various embodiments can include a programmable current sink circuit that comprises a digital-to-analog converter (DAC). The DAC is programmable to set an adjustable magnitude of current sink so that a proper amount of current is jointly sunk from a plurality of inputs to generate a total sink current. With the adjustable current sink, redundant inputs, such as dual modular redundancy or triple modular redundancy, or simplex inputs can jointly sink the proper amount of current.
