Advantages to precise input common mode voltage control to high performance high speed ADCs

All modern high speed ADCs need an input common mode voltage for their differential inputs that must fall within some acceptable range for correct operation. This is sometimes a trivial issue where ...

DC-DC Converters Suppress EMI: Minimizing EMI at its Source

Higher current demands and higher operational speeds are placing greater demands that switching power supply EMI be suppressed at its source before it is allowed to propagate into other circuits and ...
