Digital Electronics Course – Part 5: Logic gates

A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

Using VHDL To Generate Discrete Logic PCB Designs

VHDL and Verilog are hardware description languages, used to describe and define logic circuits. They’re typically used to design ASICs and to program FPGAs, essentially using software to define ...

Digital Electronics Course – Part 9: Level Translators and Different Logic Levels

As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...

It’s Hot, Powering, And Burning CMOS Logic Circuits

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...
