2.2 Unraveling the practical mysteries behind RF converter front-ends
Let’s face it: high-speed ADCs operate differently. Their analog inputs are voltage-input-sensitive devices that leave RF engineers scratching their heads about how to design the analog input front-end interface. Adding to this confusion, analog input interfaces are typically differential by nature and host a time-varying type of input impedance as the internal sampling switch opens and closes at the speed of light. This presentation will unravel these common confusions.
