Structure and Working Principle of Field Effect Transistors07 April 2025
A field-effect transistor is a semiconductor device that uses the electric field effect of the control input circuit to control the output circuit current and is named after it. Because it only depends on the majority carrier in the semiconductor to conduct electricity, it is also called the unipolar transistor. FET English is Field Effect Transistor, abbreviated as FET. There are two main types: junction FET (JFET) and metal-oxide-semiconductor FET (MOSFET).
Working Principles and Applications of Pressure Sensors07 April 2025
A pressure sensor is a device that can sense a pressure signal and convert the pressure signal into a usable output electrical signal according to certain rules. The pressure sensor usually consists of a pressure-sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.
Varistor: Definition, Function, Working and Testing03 April 2025
A varistor is a device with a non-linear volt-ampere characteristic. When the voltage applied to the varistor is lower than its threshold value, the current flowing through it is extremely small, which is equivalent to a resistor with infinite resistance, vice versa. The most common varistor is a metal oxide varistor (MOV).
What is Brushless DC Motors (BLDC) ?03 April 2025
Brushless DC (BLDC) motors represent a significant advancement in electric motor technology, combining high efficiency with superior performance characteristics. Unlike their brushed counterparts, BLDC motors eliminate mechanical commutation components in favor of electronic commutation systems, resulting in enhanced reliability and operational longevity. These motors have become increasingly prevalent across various industries due to their excellent torque-to-weight ratio, improved electrical efficiency, and precise control capabilities (Miller & Hendershott, 2022).
Sensor Basics: Classification, Working Principle and Application02 April 2025
A sensor is a detection device that can sense the measured data and convert it into electrical signals or other required forms of information output according to particular rules, in order to meet the requirements of data transmission, processing, storage, and display, as well as recording and control. Sensors are frequently categorized based on their functioning principle, input data, and application scope. They may be loosely split into three types based on their diverse functioning principles: physical type, chemical type, and biological type.
What is Color Ring Inductor? How to Read Inductor Color Code?01 April 2025
Hello everyone, I am Rose. Today I will introduce color ring inductor to you. A color ring inductor, also known as a color code inductor or a color ring inductor, is a self-inducting component. Together with a capacitor, the inductance coil (color ring inductance) frequently creates a resonant and filter circuit in the circuit.
Manifold Absolute Pressure (MAP) Sensor: Working Principles, Structure, and Types31 March 2025
Manifold Absolute Pressure Sensor, referred to as MAP sensor. The MAP sensor is an indirect air flow meter, and its signal is one of the important signals for the basic fuel injection control of the engine.
Introduction to Synchronous Counter and Asynchronous Counter31 March 2025
The counter is mainly composed of flip-flops. According to the flip order of flip-flops, the counter can be divided into synchronous and asynchronous.
What is latch?28 March 2025
Hi, fellas. I am Rose. Welcome to the new post today. A latch is a type of pulse-sensitive memory cell circuit. They have the ability to change state in response to a certain input pulse level. This article mainly introduces latch in six aspects.
What Sensors does a Car Engine Have?28 March 2025
The engine sensor control system contains many types of sensors, such as temperature sensors, pressure sensors, position and speed sensors, oxygen sensors, and knock sensors, etc...
What is a Delay Circuit? 6 Types of Delay Circuits Explained28 March 2025
In the digital circuit design, it is sometimes necessary to delay a signal for a period of time and another signal. The typical delay circuit is a string guide, and the delay time is the sum of the delay of each guide.
What is a Cascode Amplifier?27 March 2025
An analog circuit's output is increased by using a cascode amplifier. The use of cascode is a common approach that can be extended to both transistor and vacuum tube applications. In the year 1939, the tern cascode was included in an article written by Roger Wayne Hickman and Frederick Vinton Hunt.
