Analog Front End Definition. The analog portion of a circuit which precedes a d conversion. Figure 1 shows a block diagram of a typical imaging system.
A typical afe starts with an input clamp. An analog front end afe or analog front end controller afec is a set of analog signal conditioning circuitry that uses sensitive analog amplifiers often operational amplifiers filters and. Analog front end afe and a digital asic.
The common mode level of the image sensor s output signal could range from 0 v to more than 9 v so the signal must be ac coupled to the afe.
These products provide a highly integ. Analog devices communications analog front end afe products are components optimized to take advantage of smart partitioning by integrating amplifiers filters receive adcs and or transmit path data conversions dacs. Afe show site wide search results for. Issue of the analog edge sm will provide a few design ideas and suggestions for an analog front end for use with high perform ance adcs suitable for high speed data capture.
