This paper presents the extensions and experimental validations of a new approach recently developed by the authors for accurate estimation of on-resistance (RDS(on)) of large lateral power MOSFET switch layouts present in on-chip DC-DC converters. This approach exploits the highly symmetric and repetitive patterns of power MOSFET layouts to generate the extracted resistance netlist efficiently resulting...
This paper presents an accurate and fast technique for the estimation of on-resistance (RDS(on)) of large lateral power MOSFET switch layouts in on-chip DC-DC converter and determination of the current distribution pattern in the switch layouts. In the proposed approach an extracted netlist is created which consists of the lumped parasitic resistances formed in the metal interconnects and the MOS...
Fast transient response is the most important requirement of the voltage regulator modules (VRMs). This paper presents a new control scheme for multiphase buck converter circuits used in VRMs. This control scheme has fast dynamic response and better load rejection characteristics compared to the conventional control scheme of interleaved VRMs. The simulation results show improvement in the transient...
