The correct flow in the basic block diagram of op-Amp is A. Complementary symmetry push pull amplifier block. B. Dual input unbalanced output differential amplifier block C. Emitter follower with constant current source block D. Dual-Input balanced output differential amplifier block Choose the correct answer from the options given below :
D$\longrightarrow$ B$\longrightarrow$ C$\longrightarrow$A
To understand the correct flow in the basic block diagram of an Operational Amplifier (Op-Amp), it's important to know the function and interaction of each block mentioned in the options.
- Dual-Input Balanced Output Differential Amplifier Block (D): This is the first stage of the Op-Amp. It amplifies the difference between two input signals and is crucial for achieving a balanced output, which reduces noise and interference.
- Dual Input Unbalanced Output Differential Amplifier Block (B): This block typically follows the balanced differential amplifier. It serves the purpose of amplifying the input signal further but with one of the outputs grounded, thus providing an unbalanced output.
- Emitter Follower with Constant Current Source Block (C): Next in line, this block acts as a buffer offering high input impedance and low output impedance. It ensures that the previous stage does not get loaded, preserving signal integrity.
- Complementary Symmetry Push-Pull Amplifier Block (A): This is the final stage of the Op-Amp, which provides the necessary output power to drive the load efficiently. It uses both NPN and PNP transistors to provide high efficiency and low distortion.
Given the typical operation and arrangement of these blocks within the operational amplifier, the correct order as per the function is:
D (Dual-Input Balanced Output Differential Amplifier Block) → B (Dual Input Unbalanced Output Differential Amplifier Block) → C (Emitter Follower with Constant Current Source Block) → A (Complementary Symmetry Push-Pull Amplifier Block)
This order is logical as it starts with a stage that provides noise cancellation and continues with amplification and buffering necessary for driving the final output stage.
Thus, the correct answer is: D → B → C → A
