I'm trying to build a simple PWM modulator to convert the analog Audio signal into an PWM waveform, the triangle wave generator works fine and i have used an AC sine wave as an audio input, with an DC offset to match with the Triangle wave reference, but couldn't get the comparator circuit into...

So I've been recently trying to build a simple class D amplifier, I've seen through the block diagrams and design considerations online, but recently came across an Amplifier design which doesn't seems to fit the majority of the circuits online. So in the input stage we use a comparator to...

Hello, I have a Class D amplified speaker I am trying to fix (circuit attached). The fault at the moment is that when the speaker is powered on, and with no input signal, one of the speaker channels half-bridge configured FET's begin to immediately overheat. Hot enough that it turns the solder...
