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 ...

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 ...

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 ...

In researching my latest article I ran across this paper about a “robust” photodiode amplifier (pdf). I use the scare quotes on purpose, since the whole article seemed a little fishy to me. The author ...

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 ...

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 ...

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 ...

Marktech Optoelectronics today announced their offering of new InGaAs quadrant and array photodiodes for laser alignment and position sensing applications. The fast response and wide operational ...

TOKYO--(BUSINESS WIRE)--Kyoto Semiconductor Co., Ltd. (President and CEO Tsuneo Takahashi, Head office: Fushimi-ku, Kyoto city), a leading optical device solution manufacturer with world-class ...
