16-bit hybrid A/D modules address digital RF, imaging, ATE Product News 6/26/2006 Post a comment Slated primarily for RF systems, here are some low-distortion 100-Msample/s hybrid 16-bit A/D converter modules. These $80 hybrids can reduce non-linear distortion in pipelined data converters as designed into high-IF radio strips, where they offer an enhanced ENOB, bestowing higher data rates. They also lend themselves to scalability, letting you include more channels in a system.
CCD and CMOS image sensor processing pipeline Design How-To 6/23/2006 2 comments After exposure to light, the accumulated charge over the entire CCD pixel array is read out at one end of the device and then digitized via an Analog Front End (AFE) chip or CCD processor. On the other hand, CMOS sensors directly digitize the exposure level at each pixel site. This digital camera front end tutorial provides an overview of image processing signal flow.
