Abstract qj|P0N{7  
The expanding market for radio-frequency personal communication devices has led to ou8V7  
the proliferation of different communication standards and a high consumer demand for low @p`*MWU  
cost, low power, small form factor devices. As a result, present research focuses on the design tDw(k[aK@  
of a monolithic receiver that can adapt to the various communications standards in a cost- ZYRZ$87jZ
