This design work can be used for a single lithium-ion battery operated portable electronic system. The input voltage range of the converter is 3.5V-5V and the maximum load current can be as high as 950mA. A high switching frequency of 1MHz is used for the design to achieve a smaller inductor and capacitor value as well as a lower voltage ripple. The functional blocks of this designed synchronous buck converter include power stage circuit, compensated error amplifier, PWM comparator, dead time generation circuit and gate driver. Based on TSMC 0.35 um process, the whole circuit system as well as each functional block are simulated and the simulation results show that the output voltage ripple of this synchronous buck converter is smaller than 10mV. At 6Ω load resistance, the synchronous buck converter has efficiency greater than 96% and at input voltage of 3.7V, the synchronous buck converter has efficiency greater than 90%. Software to be used is cadence and all simulations must be done by teamviewer on my laptop
Hello,
I have some practical knowledge with related to this project work. Also there some friends who in research fields to support also. It is enough 5 days to complete this task..
Thank you.
