Dreaming of a Single-Chip Mobile Phone

The Feature has an article by Mark Frauenfelder, which states that “two mobile phone components — antennas and frequency oscillators — have stubbornly refused the join the rest of the circuitry that has moved onto wireless transceiver chips. But research at the University of Michigan could lead the way to a single-chip solution.”

The next step, says Michael Flynn, who heads the wireless research group at UM, is to put both the slot antenna and the RF MEMS oscillator onto a single wireless transceiver chip. Besides making traditional mobile phones more useful, a single-chip transceiver could foster the development of smaller smart dust motes and tinier non-traditional mobile devices as well. Obviously, the idea of a phone small enough to fit inside your ear canal is repugnant to most people, but a single-chip transceiver will certainly lead to innovations no one has thought of yet.
