The Circuit Diaries

These are assorted notes about electronic circuit design. They are here to document my explorations, also for my own future reference. The notes are not in strict chronological order, and I might be updating them randomly.

• MCU PWM audio
• Buck booster for the magic eye
• LTSpice magic wormhole
• Op-amp parameters
• Composite video splitter
• Oscilloscope graphics with DAC
• Hunt for the perfect triangle wave
• Class D amp from scratch
• Opamp+BJT push-pull amplifier
• 24V tube amp, yes or no?
