We present a highly-configurable, low-power, low-area, SAW-less TX architecture that is based on a dynamically-biased power mixer. All FDD/TDD bands for 4G LTE and 3G WCDMA/HSPA are supported in addition to 2G quad bands. The power-mixer bias current is dynamically adjusted based on the instantaneous baseband signal swing using a fully-differential hybrid(More)
This thesis is devoted to the study of string theory in AdS 3 and its applications to recent developments in string theory. The difficulties associated with formulating a consistent string theory in AdS 3 and its underlying SL(2, R) WZW model are explained. We describe how these difficulties can be overcome by assuming that the SL(2, R) WZW model contains(More)
