Class-D amplifiers are widely used in automotive audio systems because of their high efficiency. In modern car sound systems, multiple amplifiers are used to provide good audio effect. However, typical class-D amplifiers have a high idle-power, which can drain the battery quickly. To solve this problem, an ultra-low idle power class-D amplifier...

Digital isolators are devices that connect one electrical system block to another over a galvanically isolating barrier. They allow electrical systems to communicate with each other even though they may operate at vastly different potentials. They also do the job of eliminating potentially damaging ground loops between the two systems. This...

This work presents a fully differential Class D audio amplifier using 2.1MHz pulse-width modulation (PWM) frequency and 425kHz LC filter cut-off frequency to decrease the cost of off-chip components. Moreover, feedback after LC filter structure is used to attenuate LC filter nonlinearities.
