摘要

In this paper, two programmable voltage-detect charge balance controls (CBC) are implemented on a buck converter. The proposed CBC simultaneously optimizes both load transient and dynamic voltage scaling (DVS) to minimize output voltage spikes and settling time. Firstly, this paper introduces a computational method that is equipped with high resolution analog-to-digital (ADC) converter to achieve better CBC performance. Secondly, an auto-tuning mechanism is introduced to achieve the same performance but with less cost for the circuit. The proposed computational CBC and auto-tuning CBC were tested on the MATLAB Simulink/ Modelsim co-simulation platform to verify the effectiveness of transient response. Simulation results show that the output voltage (Vout) spontaneously follows the DVS function at various Vout levels (from 0.9V to 1.2V) with very fast transient response.
