class D amplifier V2

The modulator section of this amplifier consist of a clock generator, low pass filter, comparator and non-inverting buffer. The input signal is biased to 2.5V and compared with an high frequency triangle wave to generate the PWM signal. The signal is then buffered before passing through a RCD network to generate dead time between the on/off pair. The gate driver drives the MOSFET gate to generate an amplifier version of the PWM. The PWM is then filtered using LC filter and finally outputs to a speaker.
