Integrated Micronode Research
Abstract
A brief focused research effort was performed to examine three critical aspects key to the feasibility of very small single chip CMOS communication nodes called "micronodes." Simulation and analyses were carried out for node operation at 2.4 GHz or 5.2 GHz to determine the practicality of on-chip antennas, adequately stable on-chip frequency references, and sufficiently low power dissipation to permit node operation with small coin batteries. The design goal was to achieve 20 m node to node and 1 km node to base station operation for uNodes approximately the size of an M&M(TradeMarked) candy. On chip monopole antenna configurations simulated at 5.2 GHz were shown to be feasible using simple geometries, while 2.4 GHz monopole antennas required more exotic configurations. Using a technique called differential chip detection; simulation showed that adequately stable frequency references could be established to support operation over the temperature and voltage operating ranges. Trial designs and simulations were performed to determine whether 5 mW operating power levels could be achieved. The results slightly exceeded the 5 mW level, but were close enough to confirm the technical feasibility of optimized designs reaching sub- 5 mW levels.
