Video current D/A converters: some fundamentals for IP use
Design How-To  
10/5/2005   Post a comment
Typical video D/A converters have 8 to 10 bits of accuracy and operate at speeds between 100 to 400 MHz. At these speeds, current D/As are the preferred architecture since current D/As are less sensitive to capacitive loads. However, a method is needed to convert the output currents into voltages. Here are design ideas on how to best accomplish this technique without losing accuracy.
