Sampling resistors have various important functions and roles in circuit design

The use of resistors in circuit design has various important functions and roles, mainly including the following aspects:

Voltage division: By connecting resistors in series in a circuit, the voltage of the circuit can be divided, thereby achieving voltage distribution and control.

Diversion: By connecting resistors in parallel in a circuit, current can be diverted to protect other components from excessive current surges.

Current limiting: Resistors can be used to limit the maximum current passing through a device, prevent overcurrent damage, and are commonly used in LED current limiting circuits.

Impedance matching: Inserting resistors between the source and load can achieve impedance matching and improve signal transmission efficiency.

Filtering: Resistors can be combined with capacitors and other components to form an RC filtering circuit, which is used to filter out high-frequency noise in signals.

Up and down: Resistors can be used to pull uncertain signals to high or low levels, while also limiting current.

Sampling resistor: used for current sampling, converting current signals into voltage signals for subsequent measurement and processing.

Protection circuit: Resistors can be used to protect circuits and prevent faults such as overload and short circuit.
