In this study, we developed a novel strategy for constructing customized cellular functions by functionally rewiring cellular input–output ... suggest strategies for using this technology ...

By using op amps powered from a bipolar supply and ground-referencing the sensor signals, the op amp’s output will be at zero ...

we use a power sensor along with a directional coupler. When it comes to 1-dB compression point measurement, by varying the input power and measuring the output power, we have to measure and calculate ...

How to use negative feedback to regulate output power from a laser diode using a simple, single op-amp based circuit ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.
