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...
Thenoise marginof a logic gate for logic level '0',Δ0, is defined as the difference between the maximum input voltage that it will recognize as a '0' (Vil) and the maximum voltage that may be applied to it as a '0' (Vol of the gate driving it). For logic level '1',the nois...
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...
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...
1. a compact solid-state device consisting of a semiconductor with three or more electrodes: performs the primary functions of an electron tube, as amplification, switching, and detection, but uses less power. 2. Also called transis′tor ra′dio. a transistorized radio. [1945–50; trans...
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...
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 ...
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...
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...
