Design of PWM with four transistor comparator for DC–DC boost converters.

The DC-DC converter is used for different applications which needs higher voltages when compared to the input source. The boost converter is one of the most efficient methods to choose DC-DC Converter in different ways. The purpose of the proposed method is to reduce the area of VLSI design logic and power consumption. Boost converter topology is difficult because it has a large component. The proposed work of four transistor comparator based PWM (Pulse width Modulator) that can be used in DC-DC boost converter, which reduces the area, and power consumption of the entire system. This proposed work calculates the parameters of boost converter and the simulation performed using different duty cycle and parameters. Simulation results shows different duty cycles with different resistance and inductance parameters using boost converter. In addition to this the result carries out four transistor comparator output which is used to reduce the boost converter circuit design. PWM is based on the proposed four transistor comparator, which is used in the Cadence Virtuoso software using conventional CMOS technology. [ABSTRACT FROM AUTHOR]
