This paper presents a new architecture for a overcurrent detection system, dedicated to fully integrated class-D audio amplifiers, that uses half the comparators than conventional architectures. A detailed implementation for a 1-W bridge-tied load (BTL) class-D amplifier, on a 0.18 µm CMOS technology is presented, showing a reduction of 28.8% in(More)
This paper presents an optimization methodology for continuous time loop-filters design applied to Class-D amplifiers. The methodology is based on an evolutionary optimization approach which integrates both the topology selection and circuit sizing by automatically generating optimal sized topologies and performance tradeoffs for the Class-D amplifier.
