What are the advantages of digital circuits compared to analog circuits? [Copy link]

The development of current science and technology has made digitalization more and more popular. For example, we often see digital home appliances, digital instruments, and even TV sets. What does this show? It shows that digital circuits do have more advantages than analog circuits. One very important point is that digital circuits consume less power than analog circuits. 34)]Transistors in digital circuits all work in a switching state, that is, they only work in the cut-off and saturation states. Although the voltage across the transistor is high when it is cut off, the current flowing through the transistor is almost zero. Although there is current flowing through the transistor when it is saturated, the voltage across the transistor is basically zero, so the power consumption of the transistor is small. Only when the current passes through the amplification area at the moment of switching between the cut-off and saturation states, there is negligible power consumption.

In addition, digital circuits also often use unipolar transistor circuits, namely MOS circuits, which are voltage-controlled devices. In digital state, transistor power consumption is smaller. The transistors in analog circuits work in the amplification area. The voltage across the transistors and the current flowing through the transistors are relatively large. In order to prevent signal distortion during transmission and amplification, a static operating point must be established for the transistors, so the power consumption is significantly higher than that of digital circuits.

Since digital circuits have low power consumption, they can have a high degree of integration and are more powerful.

In addition, the advantages of digital circuit signal processing are stability, no need for debugging, easy setting and modification, and easy implementation of adaptive processing. These are the advantages of digital circuits over analog circuits.
