Seven Steps To Successful Ultra-Low-Light Signal Conversion

The photodiode remains the basic choice for photo-detection among solid-state detectors (Fig. 1). It is widely used in optical communication and medical diagnosis. Other applications include color measurement, information processing, barcodes, camera exposure control, e-beam edge detection, faxes, laser alignment, aircraft landing aids, and missile guidance. 1. The energy transmitted by light to a photodiode sensor generates a current …

Tighten The Gap Between ADC Datasheet Specs And The Real World

All high-speed analog-to-digital converter (ADC) datasheets show specified performance that really should be considered an ideal response under the best of all possible test conditions. Most systems can’t use coherent sampling, super-narrow bandpass filtering, or very high insertion-loss filters just before the ADC. Upon realizing that those ADC datasheet numbers can’t be achieved in real systems, designers then must take …

USB FM Radio design with C85F2 Microcontroller

USB FM Radio design is intended as a reference for incorporating FM radio functionality into a USB product. The design consists of two major components, the Si47 FM radio receiver and the C85F2 microcontroller with a built-in universal serial bus (USB) peripheral. Due to the high level of system integration of both of these components, the total design is very …
