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.

This paper presents a thermal-aware floorplaning tool for integrated MOSFET power stages. It generates area and power optimized transistors, automatically complying with design rules. The tool also creates placement solutions of power stages, optimizing for area, wire-length and temperature spread. The tool creates technology independent layouts, and(More)
