摘要：
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.
