Ultra low power control circuits for PWM converters
Abstract
Low voltage high-efficiency DC-DC conversion circuits are integral components of battery operated portable systems. This paper presents the design of a pulse width modulated (PWM) controller for a milliwatt level DC-DC converter. Low power control circuitry is constructed by utilizing a delay line based PWM generator and low-resolution feedback. A DC-DC converter has been fabricated which delivers 5 mW at 1 V, while achieving an efficiency of 88%. The PWM consumes only 10 /spl mu/W.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
