Power Losses in High Frequency Switching-Mode Regulator for Integrated Circuit Applications

In this paper an integrated buck switching-mode regulator for modern communication portable devices is presented. The switching frequency
$f_{s}$
of the circuit, designed on AMS 0.35 µm technology with Cadence, is equal to 200 MHz. Power losses sources in CMOS IC are discussed and evaluated as a function of circuit's parameter. The energy dissipations and efficiency of the designed converter are investigated as a function of the load current
$I_{L}$
