Abstract: The systems and methods discussed herein related to digital to analog conversion. A digital to analog conversion circuit can includes a digital input, an analog output, and a cell array. The digital to analog converter can also include an integrator, an analog to digital converter (ADC), and a summer coupled to the ADC, and an adaptation circuit coupled to the summer. The adaption circuit provides controls signals to the cell array.

Abstract: A decision feedback equalizer (DFE) and method include at least two paths. Each path includes the following. An adder is configured to sum an input with a first feedback tap fed back from a different path. A latch is coupled to the adder to receive a summation signal as input. The latch includes a transparent state, and an output of the latch is employed as the first tap in a feedback path to an adder of a different path, wherein a partially resolved first tap in the feedback path is employed during the transparent state to provide a soft decision to supply correction information in advance of a hard decision of the latch.
