In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a ...

Figure 14: Voltage Output Photodiode Circuits The outputs of the photodiode circuits in Figure 14 are voltages, proportional to incident light, which may be amplified by an operational amplifier or ...

How to stabilize transimpedance amplifiers used to convert photodiode current output to voltage. Fig 1. Shown is a basic TIA circuit used in dual-supply systems. Fig 2. Figure 1’s TIA circuit ...

Panasonic's new Lumix DMC-GF5 incorporates the newly developed 12.1-megapixel Live MOS sensor which features high sensitivity signal processing. Both photodiode circuit and readout circuit are also ...

Increased light sensitivity using photodiodes Uses vary from tiny sensor elements for cameras or for bioanalytics to large-scale, quality control applications.

This circuit was developed to aid manufactures of optical equipment in using linear detectors arrays with their optical setup without requiring specialised knowledge of electronics. These circuits ...

A G-M tube is not the only game in town though, and even the humble photodiode can be pressed into service. [Robert] gives us a good example, with a self-contained radiation detector head that ...

Introducing a new series of gain-stabilized Silicon Avalanche Photodiodes S15415, featuring a built-in temperature compensation function inside the chip. This feature enables a constant gain, ...

The negative input of comparator IC4 is connected to the modified signal using the peak detector circuit. Components IC3, D1, and C6 are used to detect and hold the maximum voltage of the input signal ...
