A New Design Methodology For Enhancing The Transient Loading Of Low Drop-out Regulators (LDRs)
International Journal of Electronics and Telecommunications, 2019 A new simple design methodology which makes LDR output nearly insensitive to jumps of the load current for long times is proposed. This methodology is tested for more than 104 seconds. Our procedure leans on cross coupling of the time second derivative of the LDR power transistor gate and drain voltages along with their currents.

Power consumption evaluation of circuit-switched versus packet-switched optical backbone networks [PDF]
, 2013 While telecommunication networks have historically been dominated by a circuit-switched paradigm, the last decades have seen a clear trend towards packet-switched networks. In this paper we evaluate how both paradigms perform in optical backbone networks
