Generation of CPU
Before understanding how the CPU works, let's briefly talk about how the CPU is produced. The CPU is made on a particularly pure silicon material. A CPU chip contains millions of tiny transistors. Transistors are chemically etched or photolithographically etched on a silicon wafer the size of a fingernail. So, in this sense, the CPU is made up of transistors. In simple terms, transistors are tiny electronic switches. They are the building blocks of a CPU. You can think of a transistor as a light switch. They have an operating bit that represents two states: ON and OFF. This switch is equivalent to the connection and disconnection of the transistor, and these two states correspond to the basic states "0" and "1" in binary! In this way, the computer has the ability to process information.
But don't think that the principle of transistors with only simple "0" and "1" states is very simple. In fact, their development is obtained after years of hard research by scientists. Before transistors, computers relied on slow, inefficient vacuum tubes and mechanical switches to process information. Later, researchers put two transistors into a silicon crystal, creating the first integrated circuit, and then the microprocessor.
The transistors in the CPU are all integrated ultra-micro transistors, and a 22-nanometer i5 may integrate billions of transistors.
To put it simply, it is to cut a whole piece of high-purity silicon, and use laser technology to cut hundreds of millions of transistors on it, (but what I want to know is! Are these transistors triodes, moss, or any other kind of transistor, What are the specific functions of these transistors, such as triodes that can amplify signals).
How a Transistor Works
Seeing this, you must be wondering, how does a transistor use the two electronic signals "0" and "1" to execute instructions and process data? Actually, all electronic devices have their own circuits and switches, the flow of electrons in the circuit or break is completely controlled by the switch, if you set the switch to OFF, the electrons will stop flowing, if you set it to ON again, Electrons will continue to flow again. This ON and OFF switching of transistors is only controlled by electronic signals, and we can call transistors binary devices. In this way, the ON state of the transistor is represented by "1", and the OFF state is represented by "0", which can form the simplest binary number.
The special order and pattern of multiple 1s and 0s produced by many transistors can represent different situations, which are defined as letters, numbers, colors and graphics. For example, 1 in decimal is also "1" in binary mode, 2 is "10" in binary mode, 3 is "11", 4 is "100", 5 is "101", and 6 is "110" and so on, and so on, this makes up the binary language and data in which computers work. Groups of transistors can be combined to store values, as well as perform logical and digital operations. Combined with the control of a quartz clock, the transistor groups perform their functions synchronously like a complex machine.

Discrete capacitors are made up of two or more electrical conductors connected by metal plates to a substrate and covered in a dielectric, polymer, or non-dielectric substance.
Discrete capacitors vary from typical capacitors in that they can be built without a metal plate beneath them.
Discrete capacitors provide a number of advantages over metallic capacitors, including the possibility to fabricate them using small-volume manufacturing techniques.Discrete capacitors are ideal for analogue electronics applications that require high-frequency oscillation.
High-frequency oscillations can have unfavourable consequences in other areas of the electronic circuitry.
If the power rating is exceeded, for example, too much power may be produced.
Furthermore, discrete capacitors' thermal design precludes failure at high temperatures.
As we learned in the lecture of BJT that transistor has three terminals i.e emitter, base and collector. To use transistor in various applications we make one of the terminals common to both input and output circuit.
So there are three transistor configurations
- Common Base Configuration
- Common Emitter Configuration
- Common Collector Configuration
The pins of 3904 and 3906 are ECB, and the pins of 9012 and 9013 are EBC.
9013 is for 3906 and 9012 is for 3904.Triode the full name should be a semiconductor triode also called a bipolar transistor.
Triode is a kind of semiconductor device that controls current.
Its function is to amplify weak signals into an electric signal with a larger amplitude and is also used as a non-contact switch transistor.The transistor is one of the basic semiconductor components.
It has the function of current amplification and is the core component of electronic circuits.
The transistor is made of two PN junctions very close to each other on a semiconductor substrate.
