Integrated Circuit Type

There are many kinds of integrated circuits, which can be divided into analog integrated circuits and digital integrated circuits according to their functions.  The former is used to generate, amplify and process various analog electrical signals;  The latter is used to generate, amplify and process various digital electrical signals.  An analog signal is one whose amplitude changes continuously with time.

For example, when a person speaks into a microphone, the electrical audio output from the microphone is an analog signal.  The audio and television signals received and amplified by radios, recorders, audio equipment and television sets are also analog signals.  The so-called digital signal refers to the signal with discrete values in time and amplitude.  For example, an electrical code signal generates an electrical signal by pressing a button, and the resulting electrical signal is discontinuous.

This discontinuous electrical signal is generally called an electrical pulse or pulse signal.  The signals running in the computer are pulse signals, but these pulse signals represent precise numbers, so they are also called digital signals.  In electronics, discontinuous signals other than analog signals are often referred to as digital signals.  At present, analog signal is the main problem in household appliance maintenance or general electronic product production.  In this case, analog integrated circuits will be the most exposed.

Detailed Introduction

According to its manufacturing process, integrated circuits can be divided into semiconductor integrated circuits, thin film integrated circuits and hybrid integrated circuits.  Semiconductor integrated circuit is an integrated circuit made on silicon substrate using semiconductor technology, including resistor, capacitor, transistor, diode and other components, with a certain circuit function;  Thin film integrated circuits (MMIC) are passive components such as resistors and capacitors made in the form of thin films on insulating materials such as glass and ceramics.

Passive components have a wide range of values and high precision.  However, it is not possible to make active devices such as crystal diodes and transistors into thin films, which limits the application of thin film integrated circuits.

In practical applications, most passive thin film circuits are composed of semiconductor integrated circuits or active components such as diodes and triodes, which are called hybrid integrated circuits.  Thin film integrated circuits are divided into thick film integrated circuits (1μm ~ 10μm) and thin film integrated circuits (less than 1μm) according to the film thickness.  Semiconductor integrated circuits, thick film circuits and a small amount of hybrid integrated circuits mainly appear in household appliance maintenance and general electronic manufacturing process.
According to the level of integration, it can be divided into small integrated circuit, medium integrated circuit, large integrated circuit and large scale integrated circuit.

For analog integrated circuits, due to high technical requirements and complex circuits, it is generally considered that the integrated circuit with less than 50 components is a small integrated circuit, the integrated circuit with 50-100 components is a medium integrated circuit, and the integrated circuit with more than 100 components is a large-scale integrated circuit.  For digital integrated circuits, it is generally considered that the integration of 1-10 equivalent gates/chips or 10-100 components/chips is small integrated circuit, and the integration of 10-100 equivalent gates/chips or 100-1000 components/chips is medium integrated circuit. The integration of 100-10,000 equivalent gates/chips or 1000-100,000 components/chips is a large-scale integrated circuit that integrates more than 10,000 equivalent gates/chips or 100 components/chips, and more than 2,000 components/chips are VLSI.

According to conduction type can be divided into bipolar integrated circuit and unipolar integrated circuit.  The former has good frequency characteristics, but high power consumption and complex manufacturing process.  The TTL, ECL, HTL, LSTTL, and STTL types in most analog and digital integrated circuits fall into this category.  The latter works slowly, but the input impedance is high, the power consumption is low, the production process is simple, easy to large-scale integration.  The main products are MOS integrated circuits.  The MOS circuit is separate

The Classification Of The IC

Integrated circuits can be classified into analog or digital circuits. They can be divided into analog integrated circuits, digital integrated circuits and mixed-signal integrated circuits (analog and digital on one chip).

Digital integrated circuits can contain anything from thousands to millions of logic gates, triggers, multitaskers and other circuits in a few square millimeters.  The small size of these circuits allows for higher speeds, lower power consumption and lower manufacturing costs compared to board-level integration.  These digital ics, represented by microprocessors, digital signal processors (DSP) and microcontrollers, work using binary, processing 1 and 0 signals.

Analog integrated circuits, such as sensors, power control circuits and operational amplifiers, process analog signals.  Complete amplification, filtering, demodulation, mixing and other functions.  By using analog integrated circuits designed by experts with good characteristics, it relieves circuit designers of the burden of designing from the base of transistors.

IC can integrate analog and digital circuits on A single chip to make devices such as analog to Digital converter (A/D Converter) and digital to analog converter (D/A Converter).  This circuit offers smaller size and lower cost, but must be careful about signal collisions.
