Abstract
We present a novel asymmetrical segmented power-stage configuration to improve the average power-efficiency of integrated converters. A decision circuit enables the segment with small-sized power transistors and a large inductor for light-load operations, and conversely, it enables the segment with large-sized power transistors and a small inductor for heavy-load operations. The integrated converter employing our proposed configuration is designed using CMOS 180 nm for 2.5–3.3 V input, 1.2 V output, and 50 MHz switching frequency. Simulation results show the proposed converter achieves a high average power-efficiency at ~73% over a wide load current range of 5–200 mA.
