Debugging Signal Distortion/Oscillation
Electrical Engineering Asked by Cdevelop on December 18, 2020
Finally built up the circuit below that I’ve been designing/toying with in LTSpice and its working OK but I’m wondering if an experienced eye might be able to quickly label what/why the oddities are in the signals I see on my oscilloscope.
I’m probably missing a crucial component/layout choice and I’m hoping its a typical beginner mistake I’m making!
Circuit
Input: 300Hz sine wave:
- I notice that with the 300Hz input, when I increase the input level
the ‘width’ of the distorted parts widens – if that is a useful
observation for me to diagnose my issue?
Input: ActualMusic:
Actual Build
- Let me know if I can/need to explain any of the spaghetti!
One Answer
Get 4 of the 6v lantern batteries. Wire as +_12v.
Retest.
Regarding stability, your only gain_stage is Q9. Install 100pF or 1,000pF from base to collector.
