MOSFET Reverse Battery Protection

You may not know how to use MOSFET as reverse battery protection. The most common method is using a diode. However, diode voltage drop is high and this will creat issue in low voltage circuits. That is the reason many use MOSFET as reverse battery protection due to its very low on state voltage drop.
Capacitor as ESD Protection

Capacitor as ESD Protection

Electrostatic discharge or simply ESD is a universal problem in electronic circuits. Capacitor as ESD protection is providing economical solution to the problem. I used to work in automotive electronics and we used high frequency capacitors to protect the exposed…
Transistor Operation Mode Determination

Transistor Operation Mode Determination

Transistor operation mode is can easily be determined by using mathematical equations. Don’t worry; these are not difficult equations. There are three operation modes to operate the transistor. These are cut-off, saturation and linear. In cut-off, the transistor is simply…
