There is another important design stage for a switching mode supply—closing the regulation loop with a negative feedback control scheme. This is usually a much more challenging task than using an LR or LDO. It requires good understanding of loop behavior and compensation design to optimize dynami...
Let us first discuss these technical specifications of resistors. These technical insights of resistors will be extremely useful in understanding applications of various types of resistors. Nominal Resistance– Any resistor is supposed to offer a known resistance or range of resistance (in case of vari...

Implementing thermal management requires the understanding of parts/materials features, comparison and examination of their performance, and use of the right parts/materials in the right places. Although this is the last issue of "Basic Knowledge of Thermal Management," we are planning to introduce ...
The circuit is not as sensitive as METAL DETECTOR MkII but gives a good platform for experimenting and understanding oscillators, feedback and tuned circuits. You can compare the effectiveness of a PCB coil with a wire-wound coil. It is pointless learning the theory about these circuits until...
