Abstract
Aspects of the present disclosure provide a voltage reference architecture. An example circuit generally includes a resistor ladder, a reference current source, and a plurality of multiplexers. The resistor ladder comprises a plurality of resistive elements coupled in series. The reference current source has an output coupled to the resistor ladder. The plurality of multiplexers have inputs coupled to one or more nodes between the plurality of resistive elements and the output of the reference current source, each of the multiplexers having an output selectively coupled to one of the inputs of the multiplexer.
