Photonic quantum technologies hold promise to repeat the success of integrated nanophotonic circuits in non-classical applications. Using linear optical elements, quantum optical computations can be ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Single-photon detectors (SPDs) with high detection efficiency have a crucial role in modern quantum optics and information science that utilize photonic qubits as information carriers 1. The ...

A custom comparator IC that has fast response time and hysteresis protects a car's engine control unit from failures on monitored peripherals that create high current conditions. In most modern cars, ...

Part 1 of this feature discussed mixed-signal integration challenges and driver-circuit concepts. With so called automatic “mixed decay” current shaping, design engineers can work around the tedious ...
