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 few ...

Optical systems have many unique attributes that make them useful for range detection and communications, but often the optical signal needs to be converted to an electrical signal as part of the ...

Photodiodes are used in a wide variety of applications to transform light into a current or voltage. These range from solar cells to optical data networks, from precision instruments to chromatography ...

The new McPherson 671MX amplifier is a high vacuum compatible, current-to-voltage converting amplifier developed specifically for use with vacuum ultraviolet Silicon photodiodes. With integral ...

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...

Analysis using spreadsheets can sometimes fill a gap in circuit simulation programs by providing a quick and reliable way to determine circuit performance along with the flexibility to display results ...

FEMTO Messtechnik GmbH supplies the variable gain transimpedance amplifier DHPCA-100 for amplifying photo currents of fast photodiodes, with a maximum bandwidth of 200MHz equivalent to a signal rise ...
