I'm designing a triangle wave generator to power a detector. The triangle wave is coming out at the right frequency (0.4 Hz), but I'm using an LM324 and the detector that I'm driving needs 100 mA to run. I tried connecting the triangle wave output to a 1k resistor, and then into the base of a transistor but the output from the emitter was only the positive half of my triangular waveform, and I need the detector to oscillate with the positive and negative peaks. I know that I could order an op amp ic that drives a higher current, but if possible I'd like to use parts that I have on hand.
I have a spice schematic attached for reference. Spice doesn't have the LM324 so I just used the LT1014 to draw up the schematic. I also attached the schematic with the added transistor.
Thanks in advance for any ideas!
