The first circuit will convert a 220V AC input to any desired output level from 100V to 220V, however the output will be a DC, so this circuit may be used for operating a foreign equipment which might be employing an AC/DC SMPS input power supply stage. The converter will not work wi...
no chip today uses a stair-step etch, so it’s a totally new process that had to be developed for 3D NAND. This etching must be precisely controlled because each via must align precisely with its polysilicon layer, and this is a huge challenge. Applied...
Look at the simple pulse generator circuit using CMOS Gates. This is a basic circuit of a multivibrator that uses the characteristics of the inverter and the charging/discharging of the capacitor C in the circuit. Although the circuit looks easy. But it is very challenging to explain it to b...
In this article I have explained how to make a simple UPS with all the bare minimum features, ensuring that it conforms with the above fundamentals and provides the user with a good quality uninterrupted power throughout the course of its operations. UPS Stages A basic UPS circuitwill have th...
Adding a bubble to the outputnegatesthe function, creating NANDs, NORs, and XNORs: They may have more than two inputs, but the shapes should remain the same (well, maybe a bit bigger), and there should still only be one output. ...
The other property is that it's very easy to build an inverter using a NAND gate.[set up NOT gate configuration]So bear with me while I drop a whole bunch of gates into my circuit here.[wire up the two input mux]I'm going to name some nodes just to make it easier. This is my...
This circuit remains broken until you put something conductive, like solder, in contact with both halves of the tip. The solder completes the circuit, also allowing current to pass through a second light. Because of electrical resistance, both the solder and the tip heat up very quickly, and...
Another way to make a corrupted or unreadable USB drive work again is to format it: Step 1. Press Windows + R keys to bring up the Run box. Type: diskmgmt.msc and hit Enter. Step 2. In Disk Management, locate the unreadable flash drive, and check its disk information. If it's ...
Understandably discouraged, Ive harbored thoughts of quitting. Rubinstein intervened, telling Ive that after Apple was recovered, they “were going to make history”. Ive still had a resignation letter in his back pocket when summoned to meet with Jobs for the first time in the summer of 1997...
An oscillator stage is perhaps the simplest part in an inverter circuit. It's basically an astable multivibrator configuration which can be made through many different ways. You can use NAND gates, NOR gates, devices with built-in oscillators such as IC 4060, IC LM567 or just utterly a 555...
