What is an Oxygen Sensor?24 April 2025
The oxygen sensor is an essential component on engines using three-way catalytic converters to reduce exhaust pollution. It uses ceramic sensitive elements to measure the oxygen potential in the exhaust duct of the car. There are two kinds of oxygen sensors in practical application: zirconia oxygen sensor and titania oxygen sensor.
Introduction to Ultrasonic Transducer: Working Principle, Types and Applications25 February 2021
One type of sound-related transducer is the ultrasonic transducer. The electrical signals are transmitted to the target by these transducers and after the signal reaches the object, it returns to the transducer. This transducer tests the distance of the object in this method, not the amplitude of the signal. For the calculation of a few parameters, these transducers use ultrasonic waves.
An Overview of Thermal Overload Relays12 October 2020
Thermal overload relays are protective electrical appliances used for overload protection of motors or other electrical equipment and electrical circuits, The thermal overload relay is mainly used for overload protection of asynchronous motors. After the overload current passes through the thermal element, the bimetallic sheet is heated and bent to push the action mechanism to drive the contact...
What is an Instrumentation Amplifier?27 March 2025
One type of IC (integrated circuit), primarily used to amplify a signal, is an instrumentation amplifier. This amplifier belongs to the differential amplifier family since it increases the difference between the two inputs. The primary purpose of this amplifier is to reduce the surplus noise selected by the circuit. Per IC pin known as the CMRRR is familiar with the ability to reject noise (common-mode rejection ratio). Due to its characteristics such as high CMRR, open-loop gain is high, low drift as well as low DC offset, etc, the instrumentation amplifier IC is an integral component in the configuration of the circuit.
Types, Structure, and Packages of Integrated Circuits23 October 2025
The type of integrated circuit can be divided according to its use, function, structure, manufacturing process, integration, and conductivity type. The structure of the integrated circuit can be learned from levels from top to bottom: system level - module level - register transfer level (RTL) - gate level - transistor level. The packaging forms of integrated circuits include SOP, PGA, BGA, DIP.
LED Driver: Function, Types, and Application01 September 2020
LED Driver refers to the power adjustment electronic device that drives LED light or LED module components work normally. Due to the conduction characteristics of the LED PN junction, the voltage and current range of the power supply it can adapt to is very narrow, and a slight deviation may not be able to light the LED, or the luminous efficiency will be seriously reduced, or the service life may be shortened or the chip may be burned.
In-depth Analysis of the Global Semiconductor Supply Chain20 January 2022
The epidemic has led to a sudden surge in demand for digital products and technological advances. The millions of digital devices we use, from smartphones to electric cars, computers, robots, and the businesses they enable, all owe their existence to complex chips built on semiconductors. The global digital economy is estimated to account for up to 22.5% of global GDP.
Structure, Types and Working of Dry Cell04 March 2021
A dry cell is an electrical power generator dependent on chemical reactions. The cell pushes the electrons to fluid from one end to the other when the two electrodes are bound in a closed way. The electron flow allows the electrons to flow into the closed system.
What is a Fixed Inductor?15 April 2021
Fixed inductors are a classification of inductors according to their structure, and fixed inductors are commonly used inductive devices. An inductor with a fixed inductance is called a fixed inductor (or a fixed coil), and it can be a coil with a single layer, multiple layers, honeycomb type, or a magnetic core. These coils are winded on the magnetic core using a wire of corresponded diameter and they are packaged with epoxy resin or plastic according to the inductance and the maximum DC operating current.
Optical Image Stabilization (OIS) Explained: Types and Working21 May 2021
In cameras or other imaging instruments, optical image stabilization (OIS) refers to the setting of optical components to avoid or reduce instrument jitter in the process of capturing optical signals, thereby improving image quality.
What is Semiconductor Package?06 December 2021
Semiconductor package is the process of assembling integrated circuits into chip final products. Simply put, it is to put the integrated circuit die (Die) produced by the foundry on a substrate that plays a supporting role, lead out the pins, and then fix the package into a whole.
What Determines the Maximum Operating Frequency of a Diode?29 June 2022
Hello, wish you a wonderful day. In this essay, we first pose the following query: what determines the diode's maximum operating frequency? In regards to the solution, the first thing we need to understand is that the junction capacitance and the reverse recovery time of the diode are two distinct concepts. The charging and discharging times of the junction capacitance cannot match the reverse recovery time. You say that, why? Let's start by taking a look at these facts.
