  • The key to solve the seven major noises inside the circuit(7)

    7. The noise of the integrated circuit There are two types of noise interference in integrated circuits: one is radiated and the other is conductive. These noise spikes can have a large impact on other electronic devices connected to the same AC grid. The noise spectrum is extended to more than 1...

  • The key to solve the seven major noises inside the circuit(6)

    6. Noise of the resistor The resistance of the resistor comes from the inductance in the resistor, the capacitive effect, and the thermal noise of the resistor itself. For example, a solid core resistor with a resistance value of R can be equivalent to a series-parallel connection of the resistor...

  • The key to solve the seven major noises inside the circuit(5)

    5. Transistor noise The noise of the transistor mainly includes thermal noise, shot noise, and flicker noise.   The thermal noise is caused by the irregular thermal motion of the carriers passing through the body resistance of the three regions in the BJT and the corresponding lead resistance. Th...

  • The key to solve the seven major noises inside the circuit(4)

    4. Interference of electromagnetic components on the circuit board Many circuit boards have electromagnetic components such as relays and coils. When the current passes, the inductance of the coil and the distributed capacitance of the outer casing radiate energy to the surroundings, and the ener...

  • The key to solve the seven major noises inside the circuit(3)

    3. High frequency thermal noise High frequency thermal noise is caused by the random movement of electrons inside the conductor. The higher the temperature is, the more intense the electronic motion will be. The random motion of the electrons inside the conductor creates many small current fluctu...

  • The key to solve the seven major noises inside the circuit(2)

    2. Shot noise generated by semiconductor devices The amount of charge accumulated in this region changes due to the change in the voltage of the barrier region across the semiconductor PN junction, thereby exhibiting a capacitive effect. When the applied forward voltage rises, the electrons in th...

  • The key to solve the seven major noises inside the circuit(1)

    1. Low frequency noise The low frequency noise is mainly caused by the discontinuity of the internal conductive particles. In particular, the carbon film resistor has many tiny particles inside the carbonaceous material, and the particles are discontinuous. When the current flows, the electrical ...

  • The key to solve the seven major noises inside the circuit

    Circuit design is a key factor in the superior performance of the sensor. Since the output of the sensor is a very small signal, if the useful signal is overwhelmed by noise, it will not be worth the loss, so it is especially important to strengthen the anti-jamming design of the sensor circuit. ...
