A photodiode-amplifier circuit with the photodiode in the feedback path is presented. It is named the PIF-circuit. No resistor is needed at the amplifier input to provide a path to ground for the ...

The errors caused by dark current are mitigated by getting rid of the accidental reverse bias present in the earlier iteration, where VCM >> VBIAS. In the zero-bias mode, the photodiode will have no ...

The Casio SK-1 keyboard is fairly well-known in the “circuit bending” scene, where its simple internals lend themselves to modifications and tweaks to adjust the device’s output i… ...

Table 1 Benefits and tradeoffs of methods to solve dynamic range challenges. Like the challenges associated with dynamic range, noise in a photodiode also can limit the smallest recoverable input ...

Optimizing Precision Photodiode Sensor Circuit Design by Analog Devices 1-08-2017 | The focus of this article is to help solve some key design issues when using photodiodes for precision measurements.
