BVdss only specifies the voltage threshold. For turn-off events, you still need to verify the voltage spike and avalanche energy. When an inductive load is turned off, the current cannot…

The Data Acquisition System (DAQ) is an indispensable part of modern electronic equipment. It is mainly used to capture signals generated by electronic devices and sensors with high precision, to…

Hardware design engineers have probably all run into this scenario: the board comes back from the fab, the chips work fine, but communication signals mysteriously start throwing bit errors. You…

I. Why Can't You Ever Tell These Two Apart? Last week while debugging a board, a new intern engineer came running over and asked me: "Is that capacitor next to…

The ISM (Industrial, Scientific, and Medical) bands are designated radio frequency bands defined by the Radio Regulations of the International Telecommunication Union (ITU). These bands are set aside for radio-frequency…

I still remember when I first started working, I designed a control board featuring a clock operating at tens of MHz and DDR at several hundred MHz. That was when…
