Power integrated circuit implementation of optimal adaptive voltage positioning scheme using progressive waveform shaping algorithm

Adaptive voltage positioning (AVP) scheme is widely adopted in the high-load voltage regulation modules (VRMs) because it helps VRMs reducing almost half the number of output capacitors for the same design without using AVP. The AVP scheme is claimed to be optimal if its voltage transient behaviour is linear by tuning the current sensing parameter (Ri) to match the value of the output capacitor eq...
