Introduction to Integrated Circuits

Thu, 02/19/2026 - 07:17

It is the purpose of this book to explain practical construction projects in these areas using the latest types of integrated circuits. Each project has been planned for simplicity and efficiency. That is, printed circuits have been avoided, the most practical hardware has been chosen in each layout, and battery operation has been utilized throughout.

Computer Circuits for Experimenters

Sun, 02/15/2026 - 14:19

This book contains complete instructions for assembling fifteen separate logic circuits ranging from simple gates to a complex decade counter. I assembled and tested all the circuits and each should operate as described if you follow the simple assembly instructions. I hope you enjoy building and operating each circuit.

Why Wi-Fi gaining over RJ45

Tue, 02/10/2026 - 11:15
Computer InterfacingRJ45 LAN Cable

The speed of data transfer on a wired connection depends on Cable, Connector and the Crimping. Ethernet over Coax (EoC) co-axial cable. Optical and Gigabit Ethernet over Optic Fibers. Copper twisted pair and others are other means of Digital Data Transfer over Ethernet. Wi-Fi and WiMax helps freeing the user from wires. Remember Wired is more secure than Wireless.

The MOSFET in Power Electronics

Power ElectronicsThe MOSFET in Power Electronics

delabs Notes - In a Circuit Module, if all Power and Signal Polarities are reversed. All NPN to PNP, All N-Channel to P-Channel and Vice Versa. All Diodes and Caps too turned around. This Topsy Turvy or Mirror Design ought to work in Theory. It has worked for some circuits in practice too in my experience. ? 

Some believe that N-Channel is more Robust than the P Type. In Bipolar Transistor NPN is more trusted for the final output stages. The NPN Transistor and N-Channel turn-on by a Positive control bias. It may be inappropriate to say this mosfet is NPN or PNP.

LM3914 - Dot Bar Display Driver

Sat, 01/03/2026 - 08:09
Integrated-CircuitsLM3914 - Dot Bar Display Driver

The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. A single pin changes the display from a moving dot to a bar graph. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors. This feature is one that allows operation of the whole system from less than 3V. LM3914 - Versatile and Easy use Display
