摘要： In one embodiment the present invention includes a method of controlling a switching regulator based on a derived input current. In one embodiment, an output current of said switching regulator is detected and used to generate a first voltage or current signal corresponding to the output current. Additionally, a switching signal of said switching regulator is detected and used to generate a second voltage or current signal corresponding to the switching signal. The resulting signals may be combined to produce a voltage or current signal corresponding to an input current of said switching regulator. The switching signal may be modified based on the derived voltage or current signal and used to control the system.

摘要： Digital-to-analog converter architecture guarantees monotonicity and partial compensation for integral non-linearity. Two stages are separated by a unity-gain operational amplifier, wherein the first stage is a 1-bit resistor string-converter, having one end at reference high voltage, and the other end at reference low voltage, and the second stage is a multi-bit resistor string converter. The architecture relieves matching accuracy necessary for 1-bit front end. Resistor mismatch is compensated by varying buffer amplifier offset-voltage, and ensuring amplifier output is halfway between reference voltages; this improves integral non-linearity, or absolute accuracy, by the amount of mismatch present in the resistor string. Buffer amplifier at output of second stage of DAC controls INL error by varying offset voltage.
