Abstract: A front-end circuit of single-photon avalanche diode (SPAD) which achieves dual active quenching and compensates the breakdown voltage shift due to temperature is presented in this article.

Abstract: This paper presents an image sensor system based on single-photon avalanche diode (SPAD) utilizing a hybrid time-of-flight ... a digital signal processing (DSP) circuit implemented on the ...

The relay module acts like an electronic switch that isolates and safely controls the AC side of the circuit. Each relay channel on the module has input control pins connected to one of the GPIO pins ...
