(2 Questions)

  • Q1. What is Zenor diode
  • Ans. 

    A Zenor diode is a type of diode that is designed to operate in the reverse breakdown region.

    • It is also known as a voltage reference or voltage regulator diode.

    • It is used to regulate voltage in electronic circuits.

    • It allows current to flow in the reverse direction when the voltage exceeds a certain threshold.

    • It maintains a constant voltage across its terminals.

    • It is commonly used in voltage clamping applications and as...

  • Q2. Units of op amp CMRR
  • Ans. 

    CMRR is measured in decibels (dB).

    • CMRR stands for Common Mode Rejection Ratio.

    • It is a measure of an op amp's ability to reject common mode signals.

    • CMRR is expressed in decibels (dB).

    • A higher CMRR value indicates better rejection of common mode signals.

    • For example, an op amp with a CMRR of 80 dB can reject common mode signals 100 times better than an op amp with a CMRR of 60 dB.

  • Q1. What is diode? Why use in circuit
  • Ans. 

    A diode is a semiconductor device that allows current to flow in one direction only. It is used in circuits to control the direction of current flow and to rectify AC to DC.

    • Diodes are used to protect circuits from reverse polarity, preventing damage to sensitive components.

    • They are used in rectifier circuits to convert AC voltage to DC voltage, such as in power supplies.

    • Diodes are also used in signal processing circuit...

  • Q2. Flip flip explained and usage?
  • Ans. 

    A flip flop is a digital circuit that stores a single bit of data using two stable states.

    • Flip flops are used in digital electronics to store data and synchronize signals.

    • They can be edge-triggered or level-triggered.

    • Examples include D flip flop, JK flip flop, and T flip flop.
