Claim 7:
8. A circuit comprising:
a reference circuit comprising a set of reference voltage nodes and comprising one or more bandgap reference elements;
a sample and hold circuit coupled to the reference circuit, the sample and hold circuit comprising a first node, a second node, a first storage element, a second storage element, a first buffer, and a second buffer, the first node coupled to a first reference voltage node of the reference voltage nodes, to the first storage element, and to the first buffer, the second node coupled to a second reference voltage node of the reference voltage nodes, to the second storage element, and to the second buffer;
a digital-to-analog conversion (DAC) circuit coupled to the sample and hold circuit and comprising a plurality of transistor pairs, wherein a first transistor of each transistor pair is coupled to the first buffer, wherein a second transistor of each transistor pair is coupled to the second buffer, wherein transistors of each transistor pair are coupled together; and
drain switching elements coupled to drain terminals of the first and second transistors of each transistor pair.
