Basic Introduction to Photocell09 April 2025
This article addresses a photocell description that includes the process, circuit diagram, forms, and applications of the photocell. The photocell is essentially a kind of resistor that can be used to adjust its resistive value depending on the strength of light. These are cheap, easy to procure as well as specifications in various sizes. Compared with other units, each photocell sensor can work differently, even though they're from the same family.
Audio Transformer-Types, Functions and Working27 January 2021
An audio transformer is an electromagnetic system designed to separate an input circuit from an output circuit and produce a signal that passes through it with filtering. A varying electromotive force (voltage) in the secondary winding linked to the other circuit is caused by this changing flux.
Near Field Communication (NFC) Explained: Working and Applications24 May 2021
Near Field Communication (NFC) is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. Devices using NFC technology can exchange data when they are close to each other. By integrating the functions of inductive card readers, inductive cards, and point-to-point communication on a single chip, applications such as mobile payment, e-ticketing, access control, mobile identification, and anti-counterfeiting can be realized by using mobile terminals.
Car Sensors: Classification and Application21 July 2020
The car sensor is the input device of the automotive computer-controlled system. The earliest car sensors are oil pressure sensors, oil quantity sensors, and water temperature sensors connected to instruments or indicator lights in the 1960s. There are many kinds of car sensors like temperature sensors, pressure sensors, flow sensors, etc., and they are applied in different applications according to their specific properties.
What is an ASIC Chip?10 November 2021
ASIC (Application Specific Integrated Circuit) is a special-purpose integrated circuit, which is an integrated circuit designed and manufactured in response to specific user requirements and the needs of a specific electronic system.
What is a Force Sensor?19 April 2021
Force sensor (force sensor) is a component that converts the magnitude of force into related electrical signals. The force sensor can detect mechanical quantities such as tension, pressure, weight, torque, strain, and interior stress. It has become indispensable core component of power equipment, engineering machinery, various working machines, and industrial automation systems.
AC/DC, DC/DC Converter Fundamental Guide28 February 2022
Hello everyone, I am Rose. Welcome to the new post today. This article mainly introduce the definition of AC and DC, AC/DC Converter as well as DC/DC converter.
What is a Decoupling Capacitor?24 April 2020
In electronic circuits, it is often seen that there is an electrolytic capacitor near the power supply pins of the integrated circuit. This capacitor is a decoupling capacitor. Decoupling capacitors usually have two functions: one is energy storage, and the other is to remove high-frequency noise.
EMI Filter: Introduction, Functions and Applications23 December 2020
Electromagnetic interference filter, also known as "EMI filter" is an electronic circuit device used to suppress electromagnetic interference, especially noise in power lines or control signal lines. The EMI filter functions as two low-pass filters: one is to attenuate common mode interference, and the other is to attenuate differential mode interference. It is top choice for electronic equipment design engineers to control conducted electromagnetic interference and radiated electromagnetic interference.
Introduction to IC Packaging06 November 2021
In recent years, IC packaging technologies have emerged and new terms have emerged. There are at least a few dozen IC packaging-related names that can be listed.
An Overview of Linear Integrated Circuits08 May 2020
A linear integrated circuit is an integrated circuit based on an amplifier. The meaning of "linear" used to indicate that the response relationship of the amplifier to the input signal is usually linear.In this essay, we’ll first introduce the development history of linear integrated circuit. And then the production process and the high-frequency technology are discussed in detail. The following two parts mainly talk about the linear integrated circuit types and forms. And the final chapter analyzes the two typical bipolar linear integrated circuit一 Lm386 and 34063.
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.
