Design and Analysis of DC-DC Boost Converter

In this study, a DC/DC Boost (step-up) converter operating in Continuous Conduction Mode is designed and analyzed (CCM). The state space averaging technique is used to analyze both the open-loop and closed-loop analysis of the boost converters in order to calculate the transfer function. The step-up converter boosts the output voltage to 4.6 V from an input voltage range of 2.9–4.5 V, and a maximum output current of 300 mA. The Pulse Width Modulation (PWM) technique generates the closed-loop control signal for a fixed frequency of 1.7 MHz. The complete system is modeled using MATLAB & Simulink and simulated in UMC 180 nm technology on Cadence Virtuoso platform.
