This paper proposes an algorithm that can maximize the total harvested energy of a single-inductor buck-boost converter operating with multiple input energy sources. It does so by dynamically adjusting the turn-on times and allocating the available time slots for the individual input sources in such a way that all the sources require equal turn-off times for the buck-boost converter to meet the zero-current...
This paper presents a ultra-low-power oscillator and pulse-width modulator circuits for a boost-converter-based energy harvester that is capable of collecting net energy even when the input power is less than 2μW. While the previously published leakage-based relaxation oscillators demonstrated 0.42μW at 3.2-MHz, their voltage swings were limited to 0.45V to prevent crowbar currents in the crossing...
This paper presents a new type of gate driver IC that can significantly reduce the gate switching loss by leveraging high-speed and low-power operation of custom integrated circuits. The gate driver itself works as a mini bidirectional buck converter, which charges and discharges the gate terminal of a power device (e.g. IGBT) by feeding a chain of short pulses whose widths gradually increase or decrease...
Emerging power-supply-on-chip applications such as on-chip DC-DC conversion, energy harvesting, and LED drivers use switching regulator ICs integrated with digital controllers. Although the resulting mixed-signal systems call for efficient system-level behavioral simulation, this remains difficult due to the fast switching and slow transients of the regulator and the high complexity of the controller...
