Minimum Mass Waveform Capture

Photo 1—The only components added to the operating Atmel AT90S2313 circuit needed to allow for waveform sampling with less than 1-μs resolution at 1-V full scale are the capacitor and two resistors. Imagine how small the circuit will be using surface-mount components.

I can capture repetitive waveforms at 1 Msps using a microcontroller’s on-chip PWM and comparator. The impetus for developing this technique came from my own need to capture repetitive waveforms using the least expensive and lowest part count means possible. … Continue reading
