摘要: The proposed power management module with 1 V low-voltage PWM controller and dynamic self-biasing mechanism is designed to integrate with ultra-wide band (UWB) system. The on-chip pre-regulator with power conditioning circuit provides a constant and noiseless supply voltage. Instead of using large external compensation circuit, the compensation enhancement multistage amplifier increases system loop gain and stabilizes the system. Moreover, the proposed self-biasing mechanism enhances the power conversion efficiency by 4 % through the handover technique. The fabricated power management module occupies 0.356 mm(2) silicon in 65nm CMOS. With the excellent line/load transient response and the highest efficiency about 93.5%, the proposed power management has the qualification to be integrated in today's system-on-chip (SoC) applications.
