MULTI-CHANNEL AMPLIFIER WITH CONTINUOUS CLASS-D MODULATOR AND EMBEDDED PLD AND RESONANT FREQUENCY DETECTOR

A continuous time Class-D modulator with an embedded programmable logic device in a forward path. The FPGA is configured to provide synchronization control by deriving a synchronization clock for the modulator and monitoring a 1-bit PWM signal for sync-lock status; monitoring the PWM duty cycle to d...
