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 ...

The first CMOS chip was created by Fairchild Semiconductor, presented at ISSCC in 1963. The logic topologies used in today’s textbooks originated in this work. P-type devices are slower than N-type by ...

Field-effect transistors based on carbon nanotubes have been shown to be faster and less energy consuming than their silicon counterparts. However, ensuring these advantages are maintained for ...

Overview of digital logic design. Implementation technologies, timing in combinational and sequential circuits, EDA tools, basic arithmetic units, introduction to simulation and synthesis using ...

When designing a chip, a designer needs to consider many tradeoffs before developing the logic. For example, if a chip is being developed for mobile applications, power becomes a very important factor ...

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 ...

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 ...

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 ...

When I was an engineering student, I was fascinated about such subjects as Analog electronics, Logic Design, Microcontrollers etc.I loved the time I spent in my college laboratories, but unfortunately ...

A new logic-level approach directly impacts board-level performance and complexity. By optimizing interconnects, fanouts and signal structures before schematic capture, a new gate-level synthesis ...
