The current gain of the transistor amplifies the photodiode current. The sensitivity of the circuit is regulated by the 10K ohm adjustable resistor RV1. The circuit is being powered by a 5 V supply ...

The increasing demand for high-speed and accurate optical detection systems has driven advancements in the design of photodetectors and related signal processing circuits. A widely used approach to ...

To ensure that the circuit measures gamma radiation and not light, cover the PIN photodiode with an opaque material. To block radiated emission from power lines, computer monitors, and other ...

The author presents a MOS linear image sensor having a high-voltage gain amplifier in photodiode pixels. The only difference between the amplified MOS image (AMI) and this new device is the transfer ...

Just looking at the values I think there is some BS going on here. [Let’s] use a current source square wave generator for the photodiode and look at the transient response. I model the R1,R2,R3,R4 ...

Fig. 1 shows the circuit of the fire sensor, while Fig. 2 shows pin configurations of SCR BT169 and photodiode. Fig. 1: Circuit of the photodiode based fire detector. The photodiode used in infrared ...

I was inspired by a DET110 from Thorlabs that I've previously used in a university lab to build a miniature version of such a useful detector. A simple photodiode detector is based around a reverse ...

That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

The instinctive reaction when measuring nuclear radiation is to think of a Geiger counter, as the low-pressure gas tube detectors have entered our popular culture through the Cold War. A G-M tube i… ...

Here, the AD8014 is used as a current-to-voltage converter with a 10-pF source capacitance. The AD8014 has a slew rate of up to 4000 V/µs, making it ideal for high-bit-rate applications.
