A gate which can offer different delays for different input-output paths through it, is known as a variable input delay (VID) gate and the maximum difference in delays of any two paths through the gate is known as "." The VID gates have a known application in minimizing the active power...
For ease of understanding of logic gates, it is customery in tutorial presentations to use diodes as logic gate on–off switches. However, in practice, integrated circuits use transistors as on–off switches in logic gates (see chapter 7). CMOS (complimentary metal oxide semiconductor) technology...
In RAM (also referred to as read-write memory, RWM), the user can write data to the memory and read the data back from the memory. The digital IC consists of a number of logic gates, which are combinational or sequential circuit elements. The logic gates may be implemented using ...
The Transistor-Transistor Logic (TTL) is a logic family made up of BJTs (bipolar junction transistors). As the name suggests, the transistor performs two functions like logic as well as amplifying. The best examples of TTL are logic gates namely the 7402 NOR Gate & the 7400 NAND gate. TTL...
Transistors are crucial components of modern electronics. When working as an amplifier, a transistor transforms a small inputcurrentinto a bigger output current. As a switch, it can be in one of two distinct states -- on or off -- to control the flow of electronic signals through an electri...
Both transistors function as a valve. If you turn it one way and the water (electricity) is able to flow, and if you turn it the other way, it does not. Both of the transistors make up the fundamental components of Logic Gates for processing digital signals in computers and other electr...
TTL was embraced for its advantages, such as low cost, solid noise margin for stable and reliable logic signal levels, ample fan-out to drive subsequent TTL gates, and modest power dissipation to keep circuits cooler and more energy-efficient. ...
The base signal is now separated into two identical laser beams for logic operation (herein, we term these two signals as A and B). For an OR gate, the threshold power of the device should be less than either the power of A or B, while for an AND gate, the threshold power should ...
CMOS devices do not produce as much waste heat as other forms of logic, like NMOS logic or transistor–transistor logic (TTL), which normally have some standing current even when not changing state. These characteristics allow CMOS to integrate a high density of logic functions on a chip. It...
