Moreover, there is a considerable effort toward integrating all this wireless functionality in a single device. Smartphones today use as many as a dozen independent radios inside them.

Tomasz Wiśniewski,Przemysław Korytkowski4; Namgoong, IEEE Transactions for Wireless Communications, 2003) have been proposed to tackle instantaneous wideband digitization. However, while time interleaving the ADCs reduces their speed, the input dynamic range (exponentially related to ADC power) remains large.
