Discrete time digital linear regulators, including low dropout regulators (LDOs) have become competitive in muti-Vcc digital systems for fine-grained spatio-temporal voltage regulation and distribution. However, wide dynamic current range of the digital load circuits poses serious problems in maintaining stability and high efficiency at all corners. In this(More)
On-chip power delivery networks (PDNs) for today’s microprocessors and systems-on-chip (SoCs), which are characterized by dynamic supply voltage, many embedded integrated VRs (IVRs), lower decoupling-capacitor, high current ranges, multiple power modes and fast transient loads are designed to minimize AC load transients and supply noise.
