Patent ID: 8487800

Claim:
A resistive digital-to-analog converter (RDAC) circuit for providing an analog output signal derived from an n-bit digital input signal, the RDAC circuit comprising: a plurality of resistive circuit branches positioned in parallel, each of the plurality of resistive circuit branches comprising: a first inverter circuit having a resistive circuit branch first end configured to receive a bit input of the n-bit digital input signal, and a second end configured to provide an output of the first inverter circuit, wherein the first inverter circuit is configured to utilize one or more retimed clocking signals, configured to be connected to a first supply voltage, and configured to be connected to a second supply voltage, a second inverter circuit having a first end operatively coupled to the second end of the first inverter circuit, and a second end configured to provide an output of the second inverter circuit, and a resistive component having a first end operatively coupled to the second end of the second inverter circuit, and a resistive circuit branch second end configured to provide an output voltage for the bit input; and an output node for providing the analog output signal, the output node being operatively coupled to each of the resistive circuit branch second ends.
