Replicating this analog laser diode driver
I'm working on an RGB show laser and currently am figuring out what to do for the laser drivers, as they need to be modulated with a 0-5 V analog signal. There are ones for purchase but are pretty ...

Is it possible to plot an equation in LTspice? I am supposed to plot an equation like this v(t)=d/dt(ln(pout(t)) + kPout(t)
In the equation mentioned above, Pout is the voltage at some output node in my schematic. Is it possible to plot the above equation? how to plot v versus time?

LASER diode driver circuit
I have some problems on understanding how this circuit works. Its aim is that of:
bias correctly the LASER diode at left
send a signal (DATA) to the LASER diode
stabilize the working point of the ...

Individually modulate two lasers diodes using sound - while using the same power suppy and preventing signal "bleed over"
I'm trying to individually modulate two lasers diodes using the same power supply. The modulation for each laser module is created by the left and right audio channels. Is there a way to do this ...

Programmable current laser drive circuit
I'm trying to design a circuit to programmably control the laser drive current from 0-200mA. The current needs to stable (<50uA variation) but with a settling time of <1us (faster if possible). ...
