Post amplifier spotlights sensitivity Product News 10/7/2005 Post a comment Micrel Inc. expanded its family of limiting post amplifiers with a 1.25 Gigabit/s device featuring 3.3-V operation with better than 5-mV sensitivity for datacom and telecom digital apps.
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.
