A research team led by Professor Huang Xingjiu at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences ...

Another simple circuits for PWM programming of standard regulator chips, this time Vout is programmable down to zero volts.

The circuit makes it possible to obtain a high signal-to-noise ratio by effectively transferring signal charges accumulated in the photodiode to a small capacitance. We fabricated and tested a CMOS ...

Impact Statement: Nowadays, the high RI anaylte fiber sensing are mainly depend on the hollow fiber core or polishing structure, which brings in low tolerance during the future fiber fusion and ...
