A pair of NPN transistors in series gives us an And gate; a pair of PNP transistors in series gives us a Nor gate; what if we use one of each? Well… let’s see.

Jul 14, 2024 · Generally, the PNP transistor can replace NPN transistors in most electronic circuits, the only difference is the polarities of the voltages, and the directions of the current …

Aug 19, 2015 · A good way to build gates with limited numbers of transistors is to use RTL (resistor-transistor logic) techniques. For example, here is a NAND gate, which can be …

Today, millions of MOSFET transistors are integrated in modern electronic components, from microprocessors, through “discrete” power transistors. The focus of this topic is the gate drive …

Dual Logic Transistor Gates: I build transistor gates a little different than most other electronics engineers. Most people when they build transistor gates; build them with only positive logic in …

Sep 18, 2017 · I'm curious, with a transistor being equivalent to two diodes, could one wire a single PNP with a pull down diode to be an OR gate? My thinking is as follows: Is this right, or …

Oct 14, 2019 · For building an AND logic gate using a transistor we would be using BJT transistors which can be further classified into two types: PNP and NPN – Bipolar Junction …

To implement a logical function of multiple signals, we build a logic gate, as shown below, by replacing the PNP of the inverter with a network of PNPs that pulls up (connects the output to …

Jan 7, 2015 · In this post, I’ll show you how to make digital gates just out of transistors, as opposed to just using ready-made integrated circuits. We’ll make an AND, OR and NOT gate, …

This schematic diagram shows a circuit of basic logic gate circuit. This PNP transistor circuit can act as OR gate or AND gate. If the input is closing of switch, this circuit acts as AND gate.
