Abstract:
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.

Claim (Index 1):
A digital-to-analog converter (DAC) circuit with a parallel impedance network, the DAC circuit comprising:\n a pair of voltage reference nodes for applying different voltage levels; impedance elements arranged in an impedance string for coupling between the voltage reference nodes to generate a plurality of voltage signals; a termination impedance path, comprising at least a first termination impedance element and a second termination impedance element, the termination impedance path coupled between the voltage reference nodes and at least the second termination impedance element coupled in shunt with the impedance string; and a switching network configured to receive a digital signal and, in response, selectively couple one or more of the plurality of generated voltage signals to generate a combined analog voltage DAC output signal providing an analog representation of the digital signal.
