Title 1: Design of High-Performance Low-Dropout Regulator ICs
Abstract: In the advent of functionally dense integrated circuits (ICs), linear
low-dropout regulators (LDOs) emerge as critical, if not vital, components.
They isolate and filter increasingly noisy switching supplies from increasingly
sensitive mixed-signal circuits, protecting phase-locked loops (PLLs), data
converters, voltage-controlled oscillators (VCOs), and the like from
power-supply noise, coupled noise, load variations, and widely variant battery
voltages, and all this while regulating its output, supplying the load, and
consuming little power. With this in mind, the aim of this talk is to show how to
design high-performance LDO ICs. The presentation therefore starts by
discussing dropout voltage, quiescent power, and power-supply rejection
(PSR). With this foundation, the material then explains and shows how to
design the series power switch, the driver, the feedback error amplifier, and
the die–package–printed circuit board (PCB) interface of the system for low
dropout, low power consumption, high PSR, and fast response time.

Title 2: Designing Tiny DC-Sourced Single-Inductor Charger–Supply ICs
Abstract: A challenge wireless microsensors and other microsystems face is
short lifetime, because tiny batteries store little energy. Although miniaturized
fuel cells and atomic sources store more energy than lithium ions and super
capacitors, they source less power, so they cannot power as many functions.
Unfortunately, their power-dense counterparts cannot sustain life for long.
Thankfully, the environment also holds vast amounts of energy, and of typical
sources, like light, motion, temperature, and radiation, sunlight produces the
highest power density, but only when available. Either way, combining
miniaturized fuel or photovoltaic cells with tiny lithium-ion batteries or super
capacitors can be more compact, reliable, and longer lasting than any single
technology. Managing a hybrid system of this sort to supply a microwatt
system, however, requires an intelligent, low-loss circuit. With this in mind, this
talk discusses the state of the art in miniaturized charger–supply systems that
draw power from an energy-dense source and supplementary power from a
battery to supply a load and recharge the battery with excess power.
