In embedded design, analog circuits can be applied in the following several ways:
1.Power management: Design appropriate power circuits, such as voltage stabilizing circuits, to provide a stable voltage for the embedded system.
2.Signal conditioning: For example, amplifying weak signals, filtering to remove noise, etc., to improve the quality of the input signal.
3.Sensor interface: Connect with various analog sensors to convert physical quantities into electrical signals and process them.
4.Driver circuit: Used to drive some external devices or actuators that require specific currents or voltages.
5.Clock circuit: Generate a stable clock signal to provide an accurate time reference for the system.
6.ADC (Analog-to-Digital Conversion) and DAC (Digital-to-Analog Conversion) interfaces: Realize the conversion between analog signals and digital signals.
7.Audio processing: Perform operations such as signal amplification and equalization in embedded systems involving audio.
8.Temperature compensation circuit: Compensate certain parameters according to temperature changes to ensure stable system performance.
9.Reference voltage source: Provide an accurate reference voltage for comparison and measurement operations.
10.Analog signal transmission: Ensure the effective transmission and high quality of analog signals within the system.
