A simple circuit modification can effectively reduce temperature-induced noise for a JFET-based amplifier at a reasonable ...

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 ...

A classic photo-sensing system circuithas a photodiode, an operationalamplifier, and a feedback resistor/capacitorpair at the front end. Recallinga circuit from another column, in thiscircuit, the ...

In the circuit in Figure 1, the red LED is on for 50 µsec, both LEDs are off for 450 µsec, the NIR LED is on for 50 µsec, and then both LEDs are off for 450 µsec. The system repeats this cycle ...

In most applications, R F and C F are fixed with values chosen to provide 45° phase margin, which will ensure stability while preserving desired bandwidth. For a variable gain amplifier, however ...
