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 ...
Linear Technology’s Glen Brisebois, winner of an EDN Innovation award for best contributed article, noticed my JFET blog post and was nice enough to send along a note and some circuits he likes for ...
For photodiode-based designs requiring high-speed operation, the OPA380 transimpedance amplifier provides a gain bandwidth of 90 MHz with an offset of less than 25 µV and an offset drift of 0.1 µV/°C.
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 ...
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 ...
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 ...
A fundamental difficulty of working with nanoparticles is that your objects of study are too small for an optical microscope to resolve, and thus measuring their size can be quite a challenge. Of ...
