Abstract
Circuitry for digital-to-analog conversion is provided. The circuitry includes a driver circuit and a weighting resistor circuit coupled to an output of the driver circuit. The weighting resistor circuit includes a first resistive sub-circuit coupled to the output of the driver circuit and an intermediate node. The weighting resistor further includes a second resistive sub-circuit coupled to the intermediate node and a common node. Further, the weighting circuit includes a third resistive sub-circuit coupled to the intermediate node and an output of the circuitry. The resistivity of the second resistive sub-circuit is equal to or smaller than the resistivity of the first resistive sub-circuit.
