Most of the traditional RF circuits are static or minimally tunable using some digital controllability. For example, high power, low power and shut down modes are available in some commercially available transceivers. If available, the tuning knobs affect different specifications in an interdependent manner, resulting in changing several specifications when only one needs to be tuned. This is not...
Modern wireless systems are increasingly incorporating adaptability to operate at low power under varying channel conditions and to increase yield under severe process variation. Effective adaptation requires built in tuning knobs in the RF front end circuits. Due to the sensitive nature of RF circuits traditional turning knobs affect more than one specification simultaneously. To ensure optimal adaptation...
