A variety of different circuit boards, circuit diagrams
The size of circuits can vary greatly, from small integrated circuits on silicon wafers to high and low voltage transmission grids. Depending on the signal being processed, electronic circuits can be divided into analog and digital circuits.
Analog circuits
Converting the continuity of physical natural variables into continuous electrical signals and operating the continuity of electrical signals through the circuit is called an analog circuit. Analog circuits process the continuity voltages and currents of electrical signals.
The most typical applications of analog circuits include: amplifying circuits, oscillating circuits, and linear arithmetic circuits (addition, subtraction, multiplication, division, differentiation, and integration circuits). Operate on continuous electrical signals.
Digital circuits
Digital circuits are also known as logic circuits
Circuits that convert electrical signals of continuity into electrical signals of discontinuity quantization and operate electrical signals of discontinuity quantization are called digital circuits.
In digital circuits, the size of the signal is a discontinuous and quantized voltage state.
Most of the Boolean algebraic logic circuits are used to process the quantized signal. Typical digital circuits are, oscillators, registers, adders, subtractors, etc.. Operational discontinuity quantized electrical signals.
-Integrated circuits are also known as IC (Integrated Circuit).
-Semiconductor circuits (generally silicon wafers), which are designed into semiconductor materials using integrated circuit design programs (IC design), are called integrated circuits. -Using semiconductor technology to create integrated circuits (ICs).

Invention of integrated circuits
Jack S. Kilby (Jack S. Kilby) The father of integrated circuits
On September 12, 1958, Kilby developed the world's first integrated circuit.
Birth of an Invention
In 1947, University of Illinois graduate Jack S. Kilby took a job in Milwaukee, Wisconsin, with a keen interest in electronics, making components for radios, televisions, and hearing aids for an electronics supplier. Outside of work, he took night classes for a master's degree in electrical engineering at the University of Wisconsin. Of course, the combination of work and classes can be a challenge for Kilby, but he says, "This thing can be done, and it's really worth the effort."
