How to Drive a Higher Current Without Op-amp IC
I am powering a detector by designing a triangle wave generator. This triangle wave is coming out at the right frequency--0.4Hz. LM324 I am using and the detector that I’m driving needs 100mA 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 and negative peaks. I know, I could order an op-amp IC that drives a higher current, but if possible I would like to use parts that I have on hand now.
I have a spice schematic attached for reference. Spice doesn't have the LM324 so I just used the LT1014 ( LT1014 Datasheet )to draw up the schematic. I also attached the schematic with the added transistor.
Thanks in advance for any ideas!
Is this a good question?
