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 ...

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 ...

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 ...

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 ...

If your introduction to digital electronics came more years ago than you’d care to mention, the chances are you did so with 5V TTL logic. Above 2V but usually pretty close to 5V is a logic 1, below ...

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 ...

The tips documented in this column are sure to help you design your circuits better; they will help with debugging, simulation, referencing, and much more Most of the time, the circuit diagrams and ...
