As micro-controller speed is increasing and its internal function is improving, full utilization of its internal resource can dramatically increase A/D conversion speed and without compromising conversion quality. MSP430F11x1 series micro-controller is exploited to increase A/D conversion speed.展开更多

The new converters en-able the pocket microcontroller system to be powered by only one +12V source,while +5V and -12V are converted from the +12V source. The basic princi-ple, voltage ratio, efficiency and ripples are analysed. Experiment and SPICE simulation are also given, which show positive results.展开更多
