Among all device characteristics, noise can be a particularly challenging and difficult design topic.This article mainly discusses the impact of clock noise on high-speed DAC phase noise. Sources of DAC Phase Noise For high-speed DACs, phase noise primarily comes from the following aspects: clock noise, power supply noise, as well as internal noise and interface … Read more
An Analog-to-Digital Converter (ADC) is primarily used to convert continuously transmitted analog signals into digital signals, facilitating rapid processing and analysis of transmitted information by digital systems (such as CPUs and MCUs). Generally speaking, the different quantization mechanisms of ADCs are one of the key factors determining the complexity and performance of ADC design, as … Read more
The purpose of this article is to introduce the theory and knowledge related to high-speed ADCs, detailing sampling theory, data sheet specifications, ADC selection criteria and evaluation methods, clock jitter, and other general system-level considerations. Additionally, some users hope to further enhance the performance of ADCs through techniques such as interleaving, averaging, or dithering. 1. … Read more
Click the above “Mechanical and Electronic Engineering Technology” to follow us A bus, known in English as “BUS”, is very much like a public bus. For instance, the route of a public bus is fixed, and anyone can take the bus to any stop along that route. If we compare people to electronic signals, this … Read more
Nowadays, infrared sensor technology has become very mature, integrating into people’s daily lives and playing a significant role. Before understanding infrared sensors, we should first understand what infrared rays, or infrared light, are. We know that light is a form of electromagnetic radiation, and based on human experience, the visible light spectrum ranges from 400nm … Read more
Smart sensors are sensors with information processing capabilities. They are equipped with microprocessors, enabling them to collect, process, and exchange information. This integration of sensors and microprocessors results in enhanced functionality compared to general sensors. Smart sensors have the following three advantages: high-precision information collection through software technology at a low cost; a certain level … Read more
The pyroelectric infrared sensor is a sensor with significant application potential. It can detect infrared radiation emitted by humans or certain animals and convert it into an electrical signal output. It is a new type of highly sensitive infrared detection component that can detect changes in the infrared energy radiated by the human body in … Read more
1. Bandwidth Generally refers to the range of signals where the sensor output response decreases to the square root of one-half of its maximum response or half of the power. Simply put, it indicates the range that the sensor can sample, and the bandwidth is the indicator of the sensor’s response range to external signals, … Read more
1. Working Principle Sensors are generally composed of four parts: sensitive elements, conversion elements, conversion circuits, and auxiliary power supplies. 1. The sensitive element directly senses the measured quantity and outputs a physical signal that has a definite relationship with the measured quantity; 2. The conversion element converts the physical signal output by the sensitive … Read more
