A technique to implement removal of dead time control circuitry from the back-end
of a digital switching amplifier system 100 and add dead time control circuitry
on the front-end digital modulator chip. The front-end dead time control circuitry
adaptively adjusts timing of the output PWM control signals 124 to optimize
performance and power consumption, i.e. operate with minimum dead time for all
transitions. The front-end dead time control circuitry controls all propagation
delays associated with the digital switching amplifier system 100.
