Abstract
A Class-D switching amplifier (,) having a ternary mode of operation. Signal processing (,) is provided to eliminate the potential of crosstalk within one channel by introducing a time delay into the system. A susceptible crosstalk point is moved away from a zero-crossing point to a higher power level, which is advantageous in low-end audio applications. A time delay is introduced to one ramp signal (RAMPB) in the first implementation (,), and an in-sync generator (,) is utilized in another implementation (,) using offset switching in the comparitors (,) to create the time delay (&Dgr;t).
