This paper present an efficient technique and mixed-level design of programmable generating accurate reference voltage. The technique comprises a second-order error feedback Σ-Δ modulators sequence, which is then smoothed by a second-order RC filter. An FPGA-based test platform for the 10-bit programmable reference is implemented for hardware(More)
In this paper, a novel state ACP (adaptive current position) is presented, which allows Buck converter to achieve fast load transient response. The PWM (pulse width modulation) and PFM (pulse frequency modulation) modes increase light-load efficiency and maintain good regulation over a wide load range. When the load rapidly changes from light to heavy, ACP(More)
