Abstract
A mixed signal receiver includes a first sample and hold (S/H) circuit having a first S/H input terminal to receive an analog input signal and a first S/H output terminal directly coupled to a first common node; a first data slicer having a first slicer input terminal coupled to the first common node; and a first data-driven charge coupling digital-to-analog converter (DAC) including: (i) a DAC input terminal to receive a first digital signal from a first digital output of the first data slicer, (ii) a DAC output terminal directly coupled to the first common node, (iii) a plurality of capacitor modules configured to be pre-charged during a sample phase, and (iv) logic components, wherein when the logic components toggle a voltage on the plurality of capacitor modules, charge is capacitively coupled to or from the first common node during an immediately subsequent hold phase.
