STMicroelectronics offers fully
integrated power modules designed to implement a BASH® amplifier
when used in conjunction with digital processors, such as the
STABP01. A sophisticated circuit implements the output transistor
power detector that, with the digital converter, reduces the power
supply voltage.
BASH® is a patented high efficiency power amplifier circuit
topology that has taken the best of class AB and D and created
a new class of its own.
