This report is a study of the effects of a commercial 0 .13[mu] process and automotive temperature corners on a synchronous DC -DC buck converter design . The basics of switching converters will be explored with an emphasis on voltage -mode controlled feedback . A Type -III compensation network is designed using transfer function analysis to compensate for the inherent double pole introduced by an LC network . The output of the compensation network will drive a pulse width modulation comparator to vary the duty cycle of the high -side PMOS and low -side NMOS transistor switches . After the synchronous buck converter design was complete , the effect of process and temperature on efficiency , output voltage ripple , inductor peak to peak current , and output voltage load response was examined . |
