Here, we demonstrate nanophotonic integrated circuits made from high-quality polycrystalline diamond thin films in combination with on-chip single-photon detectors.

Under Geiger mode, APD's strong capacitive response to sub-nanosecond gating has to be rejected through purpose-designed readout circuit so as to enable detection of weak photon-induced avalanches.

Interestingly, most of the electronics were a small disguised AM radio. BTW, one of the cleverest circuit for an 8pin PIC I ever saw was a metal detector using an LC connected to its external ...

If your system's signal processing requirements in-clude peak detection and amplification, consider a simple circuit that will satisfy both needs and save hardware. The single ...
