I'm doing a project that basically transfer the power from a laser and light up an led using it.
The power output we are getting from the laser is at most 0.45V and 0.6mA (we used photodiode to receive the power.)
We used a buck booster that requires 0.7V and 3mA to make an led glow. As we are only allowed to use BJTs that's the best buck booster circuit we can make.
So my problem how I boost 0.45V and 0.6mA to 0.7V and 3mA so that I can feed that into the buck booster?
If you have any other solution to transfer power from the laser and make an led glow, please suggest them.
