Abstract
A system is disclosed which provides feedback voltage DC level cancelling for a configurable output of a DC-DC switching converter. By simplifying the design, the operational amplifier can be used for a wider output voltage range. Extension of the usage case to a Boost DC-DC switching converter can give noticeable performance improvements. Offset introduction using a flying capacitor is attractive because it does not require trimming. The proposal also allows for improvements for DC-DC switching converters designed for lower supply voltages, with no decrease in the differential input signal swing.
