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 pins of our product. Exposed pins are the one accessible to users. There are several ways to protect devices from

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 not conducting; so it is not a problem to send the transistor in this region. You can simply do that

Control Tuning Using Simulink Auto Tune Feature

One of the easiest methods to tune a controller is through automatic tuning. This is the principle of control tuning using Simulink auto tune feature. Unlike root locus tuning in Matlab, control tuning using Simulink auto tune feature is very easy to do and can be done in a short duration only. However, you still need to know the plant

Control Tuning using Root Locus Editor in Matlab

There are few methods to do control tuning in Matlab. One of these is control tuning using root locus editor in Matlab SISO feature. Unlike control tuning using Simulink which is automated, control tuning using root locus editor in Matlab is a manual tuning. On below figure, the upper left box  is the root locus editor where you tune your
