Design and simulation of the control architecture of a fully integrated Single Inductor Multiple output (SIMO) DC-DC converter

In the nanoscale technologies, the on-chip Power Management design strategy as a part of a System on Chip is becoming extremely important. Because the value of integrated passive components are low the DC-DC converter operates at a switching frequency as high as 200 MHz. The control architecture of a fully integrated Single-Inductor Multiple-Outputs boost like converter in a CMOS 65 nm technology is presented in this paper. The DC-DC converter counts with a step-up and a step-down outputs, but it can be easily extended to more outputs. The circuit implementation of each converter's blocks and the complete system simulation results are presented in this paper.
