Analysis and Optimization of the Two-Phase Series Capacitor Buck DC-DC Converter
… switching topologies at full load. A two-phase series capacitor buck converter (2-pscB) was introduced to power laptops as low-voltage and high-current Voltage Regulator Modules (VRMs) as well as non-isolated Point-of-Load (PoL) converters. The current sharing concept is the main feature of this …

Theoretical Analysis and Design for the Series-Resonator Buck Converter
… powering high-current and low-voltage chips. The Series-Capacitor Buck (SCB) converter doubles the duty ratio and equalizes the current between the two phases. Hard switching has hindered efforts to reduce volume via increased switching frequency, although a monolithically integrated SCB converter …

Out-of-Loop Compensation Method for Op-Amps Driving Heavy Capacitive Loads
… This work considers the converse addition of a series capacitor to instead lower the load capacitance seen by the op-amp, a seemingly complementary method that achieves the same goal. A generalized, composite compensation method is developed that uses both the shunt resistor and series …

Processing Effects for Integrated PZT: Residual Stress, Thickness, and Dielectric Properties
A series-capacitor model accounted for the observed dilution in room-temperature K from >900 to ∼600 as film thickness decreased, but could not account for the absence of the expected dielectric anomaly at high temperatures. Instead, a stress-induced distributed phase transformation related to …
