چکیده

Linear voltage regulator is inevitable in most electronic systems and demands low power and low area. A low dropout (LDO) linear voltage regulator is proposed in this paper by utilizing Current Feedback Amplifier (CFA) technology. The design achieves low power and low area by reducing the internal compensation capacitor and resistors. The simulated result shows that the design consumes only 567.1370pW which is 35% less than the reference circuit. The design also achieves low area and higher gain. Streszczenie.
