What types of coils are using in smartphones:

A coil, or inductor, is a passive electronic component that stores energy in a magnetic field when electric current flows through it. Coils are commonly used in smartphones to perform various functions, such as charging the battery, connecting to wireless networks, and providing electromagnetic shielding. They can be found in the power management, audio, and radio frequency (RF) sections of the device. Coils are also used in other electronic devices, such as laptops, tablets, and smartwatches.

Different types of coils are used in smartphones for various purposes such as: in this blog post we'll learn what coil, use & coils are used in smartphones! 

Boost coil in smartphones

types of coils are used in smartphones

A boost coil, also known as a step-up coil, is a type of inductor used in the power management circuit and display light section of smartphones to increase the voltage level of the battery and also increase the voltage⚡for display graphics and lights, between 5.25v and up to 25 voltages. This is done to ensure the voltage level is high enough to properly power the device's components, such as the processor and display.

Boost coils work by utilizing the principle of electromagnetic induction. When a current flows through the coil, it creates a magnetic field. When this magnetic field collapses, it induces a voltage in the coil that is higher than the input voltage. This allows the boost coil to step up the voltage level to a level that is suitable for the device's components.

- What types of coils are used in smartphones?

There are different types of coils are used in smartphones for various purposes such as:

Inductors: used in the power management circuit to regulate the voltage and current flowing through the device.

Transformer coils: used in the charging circuit to convert the incoming AC power into the DC power that is used to charge the battery.

Antenna coils: used in the wireless communication circuit to transmit and receive radio frequency signals.

Receiver coils: used in the near-field communication (NFC) circuit to receive data from other devices.

Motor coils: used in the vibration motor to provide haptic feedback.

Speaker coils: used in speaker to produce sound

Receiver coils: used in receiver to receive the signal and convert it into an electrical signal.

Buck coil in smartphones

A buck coil, also known as a step-down coil, is a type of inductor used in the power management circuit/section (PMU) of smartphones to decrease the voltage level of the battery. This is done to ensure that the voltage level is appropriate for certain device's components such as the sensors and camera. Buck coils work by utilizing the principle of electromagnetic induction. When a current flows through the coil, it creates a magnetic field. When this magnetic field collapses, it induces a voltage in the coil that is lower than the input voltage. This allows the bucking coil to step down the voltage level to a level that is suitable for the device's components.

Buck-boost coil is also a type of inductor that can work as a buck or boost coil depending on the circuit, it can step up or step down the voltage level as needed, and it's useful in situations where the input voltage level is uncertain and can vary.

Filter coils in smartphones 

Filter coils are used in smartphones to filter out unwanted electrical noise or interference. They are typically used in the power management circuit, audio circuit, and wireless communication circuit.

EMI filter coils: EMI stands for Electromagnetic Interference, These coils are used to reduce the interference caused by electromagnetic radiation that can affect the performance of the device.

LC filter coils: LC stands for Inductors and Capacitors, These coils are used to filter out unwanted high-frequency noise, it's commonly used in audio circuits to improve the sound quality.

RF filter coils: RF stands for Radio Frequency, These coils are used to filter out unwanted radio frequency signals that can interfere with the wireless communication circuit.

Common mode filter coils: These coils are used to filter out the unwanted common mode noise that can affect the performance of the device.

All these filter coils work by utilizing the principle of impedance matching, where the impedance of the coil is adjusted to match the impedance of the circuit thus reducing the unwanted noise.
