Modeling of AC-DC converter using 0.18 μm CMOS technology

This paper proposes a modeling of low-power CMOS transistors, which are suitable for AC-DC converter applications. First section described DC analysis of input and output device of CMOS transistor using Spectre simulation tool from Cadence Design Systems. After that, advanced CMOS transistors have been applied onto development of low-voltage CMOS AC-DC converter with minimized voltage drop and power consumption. The input voltage is set to 1.0 V and the operating power supply frequency is 50 Hz. As a result, the CMOS rectifier has gained 94 % of power efficiency and very small voltage drop, 39 mV with purely resistive load.
