A new transient analysis simulator for digital class D amplifiers, which significantly reduces the simulation time (more than ten-fold), and which provides an accurate and robust audio performance analysis, is presented in this study. This simulator, called a hybrid simulator, is of special interest because it provides a better compromise between time and accuracy when compared with previous work. This simulator consists in keeping the most representative states of the transient simulation to process an optimal simulation. The results obtained by this new technique are compared with standard transient simulations (Eldo) and with experimental measurements. The circuit under test has been designed on 0.13 m CMOS technology and, an FPGA is used for digital modulator implementation.
