Abstract

See full text

Embodiments of the disclosure can provide digital-to-analog converter (DAC) termination circuits. A single or multiple parallel impedance networks can be coupled to a DAC to reduce the DAC's AC impedance, increase the DAC speed, and reduce the DAC settling time. The parallel impedance networks can be coupled to one or more of the DAC terminals in termination specific cases, or to nodes within the DAC. In an example, one-sided T-termination can be used with a single termination impedance path coupled in parallel with the DAC terminals, for reducing AC impedance at the DAC reference terminals, increasing speed, and reducing settling time. In an example, multiple impedance networks can be used in an H-bridge termination solution, which can be useful for high resolution DACs with or within a high voltage range.
