Isolated USB-to-UART converter builds in 20 minutes for $20
05.23.2016 · Circuits
I stood in stunned silence at the smoke billowing up from the hardware on the workbench. Just moments before, it had been operating as expected, before self-destructing with a sound that can only be compared with a gunshot. The failure of the hardware under test had an unexpected consequence: the computer that had been using a USB-to-UART converter to communicate with the hardware experienced a USB fault that was not recoverable...

Series-LC-tank VCO breaks tuning-range records
05.19.2016 · Circuits
This Design Idea applies a novel topology to an oscillator. It uses a series-connected LC tank circuit to give the circuit a higher tuning range than circuits that use a parallel-LC connection. The architecture of the oscillator permits wide frequency swings, well beyond the capabilities of the best hyperabrupt varactor...
