Circuit Diagram Above figure shows the circuit diagram of dark detecting LED. This circuit shows how we can convert a simple astable mode circuit to a “ dark sensor ”. We just need to add an LDR and a ...

Working of Zero Crossing Detector Circuit In a Zero Crossing Detector Circuit, the non-inverting terminal of the Op-amp is connected with the ground as a reference voltage and a sine wave input (Vin) ...

We present a compact design of a Single-Photon Avalanche Diode (SPAD) detector with a Passive Quenching Active Reset (PQAR) circuit for reducing the Dark Count Rate (DCR). Fabricated in 0.11μm CMOS ...
