Small-Signal Analysis and Optimal Design of External Ramp for Constant On-Time V $^{\bf 2}$ Control With Multilayer Ceramic Caps

Energy harvesting circuit with input matching in boundary conduction mode for electromagnetic generators

“…Although V 2 control has several advantages, V 2 control may suffer from sub-harmonic instability. One possible reason is small ESR of output capacitor [13]. When the ESR is small, its voltage ripple won't be able to dominate the output ripple anymore and thus can't be used to sense the inductor current.…”

An Effect of Output Capacitor ESL on Hysteretic PLL Controlled Multiphase Buck Converter

“…As the low ESR capacitor is used, some technique to substitute the low ESR drawback should be used. The most common techniques are: 1) RC ripple reconstruction networks [12], [13], 2) on-chip ramp generators [13].…”

A Generalized Model of Nonisolated Multiphase DC–DC Converter Based on Novel Switching Period Averaging Method

“…Also there can be other applications, such as design of state observer [40] for NMDCs to eliminate current sensors in each phase.
