Hi everyone,
I am trying to boost the output of my TIL38, an IE LED emitter, with the help of an NPN BJT, 2N3904. The maximum current the TIL38 can handle is 150mA according to the datasheet and I am trying to boost the current through it to 100mA.
I connected the circuit below (please ignore the .nxp file as it is not in use):
In real life, I am feeding in to the base of the BJT, a 1kHz sine wave from a Wien Bridge Oscillator, with Vpp of 1.64V, Vmin = 1.8V to Vmax = 3.44V.
The output from simulation above is:
However, I am not getting an output from the oscilloscope in real life.
May I ask if this is due to a difference between simulation and the working of the circuit in real life?
Thank you.
