Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
The role of digital-to-analog converters
Real-world analog signals, such as temperature, pressure, sound, or images, are constantly being converted into digital form that is easier to store, p...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[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]
This article discusses how to use an ultra-low-power RF transceiver chip from Zarlink Semiconductor for pacemakers, neurostimulators, drug pumps, and other such implantable medical devices t...[Details]
With the rapid development of digital technology, various digital display screens have emerged, including LED, LCD, DLP, etc. There are various control systems for various digital large screens, in...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[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]
Introduction
