Common models of analog integrated circuits, the difference between analog integrated chips and digi

Signal Different Analog Chips: Analog chips are used to generate, amplify, and process various analog signals. Digital chips: Digital analog chips are used to generate, amplify, and process a variety of digital signals.

In the digital chip, the MOS transistor usually works in the cut-off region or the deep linear region, which is the equivalent switching function; In analog chips, MOS usually works in the saturation region, subthreshold region, and linear region. Further, MOS transistors behave differently depending on the slight difference in the bias voltage.

The difference between the two is as follows: refers to different analog integrated circuits: integrated circuits composed of capacitors, resistors, transistors, etc., which are integrated to process analog signals.

Digital integrated circuit: It is a digital logic circuit or system made by integrating components and wiring on the same semiconductor chip.

Tens of thousands of integrated circuit chips are divided into three acres, analog circuits, digital circuits, and storage circuits. It can only be said that any circuit that outputs 0 or 1 (high or low) is a digital circuit, and the typical 74 series is available. Everything else is analog or memory circuitry.

Digital integrated circuits: mainly modules for digital signal processing. As; It is an integrated module for processing data of 2 near-system, 8-near-system, 10-near-system, and 16-close system in the computer.

CMOS: It is a manufacturing process that uses a "insulation deficit-sensitive gate field-effect triode" as the main device for chip manufacturing.

An analog signal is a signal that is continuous in time and continuous in amplitude; A digital signal is a time-continuous, amplitude-quantized signal. The two can be converted to each other. Digital signal processing or computation can be implemented by software, which is flexible and non-destructive.

Pin resistant analog circuits cannot. The anti-interference and anti-interference ability of digital signals is stronger than that of analog signals.

Analog integrated circuit products are divided into three categories: the first type is general-purpose circuits, such as operational amplifiers, multipliers, phase-locked loops, active filters and digital-to-analog and analog-to-digital converters; The second type is special circuits, such as audio systems, television receivers, video recorders and communication systems. The third type is monolithic integrated systems, such as monolithic transmitters, monolithic receivers, etc. Analog integrated circuits also include circuits consisting of charge-coupled devices, switching capacitor circuits, and switching current circuits.

These circuits apply analog sampling techniques, also known as sampled data circuits. They are easy to obtain stable and accurate time constants, easy to achieve high-precision calculations, and have been widely used in analog signal processing and communication systems.
