Question

Which among the following amplifier circuits exhibit the output voltage in the form of phase inversion?
A. Adder
B. Substractor
C. Integrator
D. Differentiator

Answer 1

Hint: It must have an amplifier circuit that is equipped with the output voltage which is equivalent to the sum of all input voltage and must have several constant gain factors for every input voltage.

Complete step by step solution:
Adder: An adder is a digital circuit with numbers attached. Adders are used in arithmetic logic units or ALU in many computers and other processors. They are often used for the measurement of addresses, indexes for lists, increment and decrement operators and the like in other sections of the processor. Although many adders such as binary-coded decimals or excess-3 can be produced, the most common adders are binary numbers. When two compliments or complements are used to display negative numbers, a move to an adder-subtractor is trivial. More logic is required around the basic adder for other signed number representations.

The output voltage of the subtractor refers to the subtractor, integrate and differentiation amplifiers and addresses the difference between two input signals, with the integrated output voltage generated by the integrated input voltage, while the differentiator output voltage corresponds to changes in input accordingly.

Hence, the required answer is Adder option A.

Note: In this answer the circuit should have an invert scalar form amplifier, with the exception of having more than one input.
In any Op-amp adder circuit, the output voltage should be the sum of all input voltages where the input voltage constant gain factor is multiple. In general, this circuit is more similar to the inverting amplifier form, except that more than one input is usable. The adder or summer Op-amp output voltage is therefore inverted.
