What is the definition of AND gates?
AND gates are parts of electronic transistor circuitry.
What are TTL gates?
TTL stand for transistor transistor logic it could be DTL for diode or any other type of family.
What is basic construction of JFET?
A Jfet stands for junction field effect transistor. It is a transistor also known for being the simpleist field effect transistor. The basic construction contains has three parts the P-type input the n-type input and a depletion layer.
Why is an ordinary junction transistor is called bipolar transistor?
Because it uses N-type and P-type semiconductor, usually silicon.The construction will either be NPN or PNP, with the different types in a "sandwich" construction.
What does transistor to transistor logic mean and what are its uses?
A: TTL-DTL-RTL are family of gates called by the name. Example TTL means Tran. trans. logic. It refers to the inputs for these gates as the type. T= Transistor D=Diode R=Resistor While they do perform the same function their characteristics in performance varies greatly.
What is multi emitter transistor?
A bipolar junction transistor with 2 or more emitters. The most common use of these was in the input section of transistor transistor logic (TTL) gates. They offered significantly higher speed and used less area on the IC chip than the diodes used in the input section of the diode transistor logic (DTL) gates that came earlier. This made TTL ICs both faster and cheaper than the DTL ICs which soon became obsolete.
How you will compare pass transistor with transmission gate logic?
The use of transmission gates eliminates the undesirable threshold voltage effects which give rise to loss of logic levels in pass transistor logic.
Why a pull up resistor is so called?
A pull up resistor is often used in an open-collector circuit, where there is a transistor that can pull to down ground, but there is no transistor to pull up to Vcc. When the transistor is off, the pull-up resistor "pulls-up" the voltage to a point where any connected circuit "sees" the voltage and "knows" the transistor is off. This is often used in circuits where many output gates can drive a single line. Any one gate can pull the line low, while all gates have to be off to allow the line to pull high. In the alternate configuration, a totem-pole system, there are two transistors, one to pull low and one to pull high. If you have multiple gates on a common line, you must three state (turn off both transistors) on the non driving gates, or there will be conflict between gates and possible damage.
What is the best way to describe the function of a typical transistor in an electronic circuit?
A transistor in a circuit can do many things. It can be used to amplify voltage signals, or current signals, create current and voltage sources, make buffers, and so on. Transistors also find a major use in logic circuits (ie, where signals can either be a '0' or a '1'), where they essentially act as a switch, and can be used to create inverters, AND gates, OR gates, and all sorts of useful components. By itself, a transistor is a three-terminal device that can control the current going through two of its terminals through the voltage applied at the third terminal. But there are many applications for a transistor in its many different configurations, which is why it is so important in modern electronic technology.
Difrance between ic and ttl?
ic refers to integrated circuits and ttl refers to transistor transistor logic. ttl is a family which provides the basic or former structure of logic gates for example different logic gates such as NAND,NOR etc can be made out with the help of transistors connected in a specific manner. integerated circuits are the combination of logic gates presented on a base with equal number of input pins . for example IC-7408 contains 14 pins
Does the NAND and NOR gates eliminates the need for other chips?
No. A large percentage of chips are DRAMs and they are primarily comprised of single-transistor cell arrays.
How many sandwiched layers of semiconductors make up a transistor?
The construction of a BJT is very simple - it is three alternating layers of semiconductor.
