摘要: The proposed power management module with a typical 1.2 V low-voltage PWM (LV-PWM) controller and dynamic voltage scaling (DVS) function is designed using 65 nm technology for integration with the ultra-wide band (UWB) system. The on-chip pre-regulator with a power conditioning circuit can provide a regulated supply voltage to the LV-controller. Moreover, the proposed handover technique can achieve the self-biasing mechanism to further reduce power dissipation. To operate in low voltage, the proposed compensation enhancement multistage amplifier (CEMA) can achieve high loop gain and ensure system stability without using any external compensation component. The fabricated power management module occupies 0.356 mm(2) silicon area with an excellent line/load transient response. Owing to the DVS function, the proposed power management can meet the power requirement in the UWB system and other RF transceiver systems.
