Abstract: Analog to digital converters (ADC) and cascade integrator-comb (CIC) filters are the basic modules in a digital intermediate frequency (IF) spectrum analyzer. The optimal output ...

Abstract: Several new approaches for multi-hit delay-line-based time-to-digital converters (TDCs) are discussed and an input-sampled TDC architecture is realized in 45-nm SOI CMOS. The TDC is ...

The library gives easy control over the 16 pins of the PCF8575 chips. Base address = 0x20 + 0..7 depending on address pins A0..A2. PCF8575C 0x20 to 0x27 need pull up in input mode. See #36, to be ...

This library gives easy control over the 16 pins of a TCA9555 device. The pins can be used for INPUT (default) and OUTPUT, and allow to set polarity. The pins can be set per single pin, or with a mask ...

I've tested and reviewed tech, pet, fitness and home gear for decades. Time stops for no one, and for no technology. There was a time when you probably preserved family memories by saving them to ...
