How many outputs are there in comparator?

How many outputs are there in comparator?

A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger.

What is the output of identity comparator?

Identity Comparator is a digital comparator that has only one output. It goes high when A = B, either both 1s (High) or both 0s (Low). This comparator can be implemented by a combination of logic gates (XNOR and AND gates) as shown in Figure 1.

How many outputs does an 8 bit comparator?

8-Bit Magnitude Comparator – ​ Comparators with three output terminals and checks for three conditions i.e greater than or less than or equal to is magnitude comparator.

How many outputs does a 4 bit magnitude comparator have?

three outputs
A comparator used to compare two binary numbers each of four bits is called a 4-bit magnitude comparator. It consists of eight inputs each for two four bit numbers and three outputs to generate less than, equal to and greater than between two binary numbers.

What are the 5 main pins of a standard op-amp?

IC 741 Op-Amp Pin Description

• Pin 1 is Offset null.
• Pin 2 is Inverting input terminal.
• Pin 3 is a non-inverting input terminal.
• Pin 4 is negative voltage supply (VCC)
• Pin 5 is offset null.
• Pin 6 is the output voltage.
• Pin 7 is positive voltage supply (+VCC)
• Pin 8 has no connection.

How do you find the output voltage of a comparator?

Remember the equation Av = -Rf/R1. The equation for voltage gain in the inverting mode is Av = -Rf/R1. Since there is no feedback resistor, the gain will be close to infinity and the output voltage will be as negative as possible ie; V-.

How many output terminals are there for a magnitude comparator?

three output terminals
Explanation: A Magnitude Comparator is a digital comparator which has three output terminals, one each for equality, A = B greater than, A > B and less than A < B.

What is the relationship between L e and g in 1 bit comparator?

So, the comparator produces three outputs as L, E and G corresponds to less than, equal and greater than comparisons. Comparators that have only one output terminal and produces the output either low or high are identity comparators.

How many inputs are there in 24 bit comparator?

Obviously, the clean way to build the 24-bit comparator would have been to use six chips (with four A/B inputs each) for the first level, and then two more chips for the second level.

How many inputs and outputs are required for a digital comparator?

Explanation: A comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. In a digital comparator, only 3 outputs are possible (i.e. A = B, A > B, A < B). So, a – b is an incorrect option.

What kind of output we get out of the following op-amp based circuit?

An operational amplifier (op amp) is an analog circuit block that takes a differential voltage input and produces a single-ended voltage output. Op amps usually have three terminals: two high-impedance inputs and a low-impedance output port.

Why do op amps have 8 pins?

Some modern single op-amps have three unused pins, and forego the offset null completely. So why don’t many modern single op-amps come in 6-pin DIP packages? They would still conform to the standardized layout, and fit in 8-pin DIP sockets. But they would take up less space in circuits designed for them.

What is a 1-bit magnitude comparator?

1-Bit Magnitude Comparator – A comparator used to compare two bits is called a single bit comparator. It consists of two inputs each for two single bit numbers and three outputs to generate less than, equal to and greater than between two binary numbers. The truth table for a 1-bit comparator is given below:

What is comparator in a circuit?

A comparator is an electronic circuit, which compares the two inputs that are applied to it and produces an output. The output value of the comparator indicates which of the inputs is greater or lesser. Please note that comparator falls under non-linear applications of ICs.

How many rows are in a 4-bit comparator?

The truth table for a 4-bit comparator would have 4^4 = 256 rows. So we will do things a bit differently here. We will compare each bit of the two 4-bit numbers, and based on that comparison and the weight of their positions, we will draft a truth table.

What is the output value of comparator?
