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 ...

In this column, we take a closer look as to how timing and delays affect our logic circuits. As part of this, we start to consider the timing diagrams presented in data sheets. As I was writing my ...

In this paper, the authors propose a MOS-BJT-NDR circuit, which can show the Negative-Differential-Resistance (NDR) characteristic in its current-voltage curve. This NDR circuit is composed of ...

Logic Gates are among the important components of a circuit. All the logical operations required to perform a particular task in an electronic circuit are carried by these logic gates. If you are an ...

Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular design, a combination of discrete and TTL logic ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

One of the most promising nanotechnologies which can replace the present transistor based CMOS technology is the Qubit (Quantum-Dot) Cellular Automata. The major advantages of this technology are ...

March 29, 1961 - LOGICAL microcircuits in transistor cans are now being offered by four major companies. Heavy research and production is being pressed by Fairchild Semiconductor Corp., Raytheon Co., ...
