This small script is a cheap and easy way to start with IoT projects. By using the great rtl_433 software and a cheap RTL-SDR receiver it will listen to all kinds of devices transmitting at the 433,92 ...
Abstract: A sixth-order dc-to-1 GHz tunable continuous-time lowpass/bandpass ΔΣ ADC in 65-nm CMOS targeting RF and IF digitizing applications is presented. The ADC achieves 150-MHz bandwidth at ...
Abstract: Time-based controllers are well suited for implementing both single- and multi-phase wide bandwidth high switching frequency pulsewidth modulation (PWM)-based dc-dc converters. They also ...
A comprehensive, modular RF tool suite running on M5Stack/ESP32-class devices, supporting both 433 MHz and 2.4 GHz operations with safe-by-default workflows.
