Abstract :
A proposed linear regulator uses a flexible control technique of output current (FCOC) to achieve 96.5% efficiency. The FCOC technique drives a flexible output current according to the output current variation and stable output voltage supply. The linear regulator fabricated by 1.2 μm CMOS process occupies 0.423 mm2. The fabricated linear regulator achieves 96.5% current efficiency and less than 6.81 mVpp output voltage fluctuation at an output current frequency from 1.8 Hz to 100 MHz
