H-bridge Class-D hum problem solved

I H-bridge Class-D works I mentioned

I was getting a rather annoying amount of 60Hz hum, probably from the microphone preamplifier.  I’ll have to play with it a bit tomorrow to see if I can avoid the hum pickup.

H-bridge Class-D works

The simplified class-D amplifier using a cMOS H-bridge works! Using an inverter chip (in this case a 74HC14N Schmitt trigger chip) to provide separate amplifiers for each nFET and pFET allows using the TLC3702 rail-to-rail comparator, despite its rather wimpy current output. 245 more words

was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered power supply would droop before the PWM cycles were complete. 167 more words
