Complementary metal–oxide–semiconductor (CMOS, pronounced “see-moss”), also known as complementary-symmetry metal–oxide–semiconductor (COS-MOS), is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. CMOS technology is used for constructing integrated Circuit (IC) chips, including microprocessors, microcontrollers, memory chips (including CMOS BIOS), and other […]
IGBT (Insulated Gate Bipolar Transistor) is a composite fully-controlled voltage-driven power semiconductor device composed of BJT (Bipolar Transistor) and MOS (Insulated Gate Field Effect Transistor), which combines the high input impedance of MOSFET and GTR The low conduction pressure drop has two advantages. IGBT combines the advantages of the above two devices, with high […]
A microcontroller (MCU for microcontroller unit) is a small computer on a single metal-oxide-semiconductor (MOS) integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as […]
Electrical Engineering: Electrical engineering is a field of study and practice that deals with the design, development, and application of electrical systems and devices. It encompasses various aspects of electricity, electronics, and electromagnetism. Electrical Circuit: An electrical circuit refers to a complete network of electrical components that forms a closed loop, allowing the flow of […]
A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities (“doping”) into the crystal structure. When […]
Low-voltage differential signaling, or LVDS, also known as TIA/EIA-644, is a technical standard that specifies electrical characteristics of a differential, serial signaling standard, but it is not a protocol. LVDS operates at low power and can run at very high speeds using inexpensive twisted-pair copper cables. LVDS is a physical layer specification only; many data communication standards and applications use it and add a data link layer as defined in the OSI model on top of it.
The liquid crystal display is a passive display. It cannot emit light and can only use the light of the surrounding environment. It only needs a small amount of energy to display patterns or characters. It is precisely because of low power consumption and miniaturization that LCD becomes a better display method. The liquid […]
The resistance of the conductor to the current is called the resistance of the conductor. Resistance (Resistor, usually represented by “R”) is a physical quantity that in physics represents the size of the conductor’s hindrance to current. The greater the resistance of the conductor, the greater the resistance of the conductor to the current. Different […]
1 Introduction In recent years, with the development of technology, the technology of thin film transistor (TFT) has been continuously developed and optimized, and the thin film transistor liquid crystal display (TFT-LCD) has quickly become the mainstream display screen in the market. However, TFT-LCD displays still have many problems, such as screen flicker which can […]
To learn embedded, you need to understand hardware knowledge, including single-chip microcomputer, ARM, FPGA, etc. Different hardware has different characteristics, and you need to understand their corresponding characteristics to be beneficial to operating applications. So what are the differences and characteristics of MCU, ARM, FPGA, and embedded? Features of MCU: 1. Due to […]
