Abstract :
This 65 nm power management module with 1.2 V low-voltage PWM controller aims to integrate with ultra-wideband (UWB) system to get high efficiency and compact size. The on-chip pre-regulator with power conditioning circuit provides a constant and noiseless supply voltage. Thus, the voltage variation of battery has less effect on the low-voltage PWM controller. The proposed compensation enhancement multistage amplifier (CEMA) increases system loop gain and stabilizes the system without off-chip compensation circuit. With excellent line/load transient response, the proposed power management has the highest efficiency about 92% and 0.995 mm2 silicon die area.
