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 ...

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 ...

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 ...

Switching algebra is easily visualized using switches since there are only two values: on and off, or true and false. In digital systems we represent these as 1 and 0, respectively. There are only two ...

The process of designing, manufacturing, and testing ICs is complex and exhaustive. The main contributors are the design and verification teams, IP vendors, and IC manufacturers. The process 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 ...
