A sub-1V CMOS DC-DC buck converter with 90% efficiency is presented in this paper. The proposed buck converter uses a digital error amplifier that can make the input voltage lower than other conventional buck converters. The buck converter uses voltage-mode control with pulse width modulation (PWM)...
