As shown in the figure below, NMOS and PMOS are used as a protection circuit to prevent reverse connection of the power supply. [1] The circuit diagram of the PMOS tube is easy to understand. For the ...
Field Programmable Gate Arrays (FPGAs) are typically composed of thousands of programmable logic cells. A matrix of wires and programmable switches interconnects the individual logic cells. A typical ...
1. Flip chip In 1998, Lumileds packaged the world's first high-power LED (1W LUXOEN device), which changed the previous indicator light application of LED devices into a new solid light source that c...
In today's society, heart disease has seriously affected people's life safety. Many patients with sudden heart attacks are threatened because they cannot get timely treatment. Traditional ECG monito...[Details]
Human body information monitoring is an emerging field. People envision developing wireless electroencephalogram (EEG) monitoring equipment to diagnose epilepsy patients. Wearable wireless EEG can ...[Details]
How can we get the highest performance from an A/D converter? The obvious answer is to use good design and board layout, but there are other techniques that can be used to improve performance. We can ...[Details]
Designers of hearing aids have stringent requirements. Hearing aids must be small enough to fit in or behind the ear, operate on ultra-low power, and be free of noise or distortion. To meet these requ...[Details]
Currently, it is impossible to dynamically obtain patient information in medical monitoring. Once the patient's condition worsens, emergency treatment cannot be implemented in the first place, and the...[Details]
Maximize instrument utilization and reduce
test times
Increasing the throughput of automated test systems can improve efficiency. Using off-the-shelf tools (COTS) such as multicore proc...[Details]
In response to a series of problems caused by the backwardness of traditional water meters, the Ministry of Construction of China has proposed the requirement of "three meters per household" for ur...[Details]
Lithium-ion battery is a widely used rechargeable battery. It has the advantages of high single-cell operating voltage, small size, light weight, high energy density, long cycle life, rapid full ch...[Details]
JTAG Technology Introduction
One disadvantage of shrinking technology is that the complexity of testing small devices increases dramatically. When the board area is large, the board is tested...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m～1kHz), audio (20Hz～20kHz), video (20kHz～10MHz), radio fre...[Details]
E6601A is Agilent's new generation of comprehensive tester platform, designed to provide low-cost calibration solutions for mobile phone manufacturers. It uses an open Windows® XP platform, allowi...[Details]
Volkswagen's electronic throttle has taken our understanding of the traditional throttle a big step forward. However, while we admire Volkswagen's new technology, which is constantly being applied...[Details]
Introduction
Wireless operators are driving demand for broadband and data rates by offering enhanced data services to increase average revenue per user (ARPU). The need to provide users with ...[Details]
Power semiconductors and reactive components (capacitors and inductors) are ubiquitous in today's electrical equipment. In normal operation, they can cause two undesirable side effects on the AC line ...[Details]
Capacitive sensing user interfaces are emerging as a practical and innovative alternative to mechanical buttons in mobile phones. While capacitive sensors can be viewed as a drop-in replacement fo...[Details]
