Abstract

Wearable healthcare systems require highly reliable and energy-efficient power management units to ensure uninterrupted operation of sensitive biomedical sensors and devices. This project presents the design of a Low Dropout (LDO) Regulator tailored for wearable healthcare applications, implemented using 45 nm CMOS technology. The proposed LDO provides a stable output voltage with low ripple and fast transient response, crucial for powering low-voltage biomedical circuits. The design employs a two-stage architecture with a compensation circuit to maintain stability across various load conditions. Stage 1, consisting of a differential amplifier with high gain, ensures accurate voltage regulation, while Stage 2, the output driver stage, supplies sufficient current to the load with minimal voltage drop. The LDO design emphasizes low quiescent current, high power efficiency, and compact area, making it suitable for integration in portable and battery-operated healthcare devices. Simulation results confirm stable operation, low dropout voltage, and effective load regulation, demonstrating the design’s suitability for modern wearable healthcare systems.
