    Abstract: A large dynamic-range Programmable Variable Gain Amplifier (PVGA) suitable for Ultra Wide Band (UWB) applications is presented. The PVGA is composed of three programmable variable gain amplifier stages followed by an output buffer. Such wide bandwidth allows our proposed PVGA to be used in multi-standard protocols. Power reduction is developed for ... Show More
