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.

Projekt i analiza regulatora napięcia o małym poborze mocy wykonanego w technologii CMOS 0.18 m Keywords: CMOS, low dropout, voltage regulator. Słowa kluczowe: regulator napięcia, low dropout, technologia CMOS doi:10.12915/pe.2014.05.45 Introduction System on Chip (SoC), modern communication systems including Wireless Local Area Network (WLAN), Radio Frequency Identification (RFID) etc are becoming increasingly popular day by day [1-4]. These systems demands low cost, high integrability and small size [5,6]. Power management is an essential device in these systems. Over-load protection, over-heat shield, stabilization, low power and low area are the essential features of the power management devices to assure the correct operation of these systems [7]. The rapid advancement of Complementary Metal Oxide Semiconductor (CMOS) technology allows power management devices to achieve these criteria [8-10]. LDO linear voltage regulator is widely used in power management devices [11]. LDOs are one of the most critical modules as it is able to provide a nearly constant DC voltage for all the electronic systems. To regulate the performance (line and load regulation) t[...]
