Abstract
Circuits for an analog-to-digital converter and methods of operating an analog-to-digital converter. A resistor digital-to-analog converter (RDAC) has a first reference node coupled to a first current source, a second reference node coupled to a second current source, an input port configured to receive a first voltage, and an output port coupled to a buffer. The RDAC is configured to generate a second voltage including a first voltage shift from the first voltage and to supply the second voltage from the output port of the RDAC to the buffer.
