An asynchronous finite-state-machine-based buck-boost converter for on-chip adaptive power supply

Abstract

In this paper we present an asynchronous finite-state machine digital controller co-integrated with an on-chip non-inverting buck-boost power converter with dynamic signal-tracking capabilities. The mostly-digital controller functionally implements a non-PWM zone-wise control law through asynchronous circuitry, thus exhibiting\ud self-timed minimum latency and ultra low power operation due to gate switching activity. Experimental results on a\ud 0.35 lm CMOS technology demonstrate an efficiency up to 80 % with a switching frequency of 2.86 MHzPeer ReviewedPostprint (published version

Voltage‐mode robust controller design for DC–DC boost converter at the presence of wide load and input voltage variations based on finite‐state‐machine model

“…This paper and the authors of [20,21] provide two intrinsically different definitions for the states of converter, which are crucial to constructing an FSM model. It concludes that the models, methods, and results of this paper are completely different with [20,21]. Fig.…”

“…Although not discussed in this paper, the proposed FSM model and the controller can also be applied to other DC–DC converters. Very recently, some applications of FSM for modelling and control of DC–DC converters have been reported in the literature [20, 21]. This paper and the authors of [20, 21] provide two intrinsically different definitions for the states of converter, which are crucial to constructing an FSM model.…”
