Abstract :
An 8-channel microsystem for transmission of 7 input biopotentials using wireless FM in the band of 94 to 98 MHz requires only 3 off-chip components. The 4.84 mm2 IC is fabricated using a 1.5 μm 2P2M CMOS process, dissipates ∼2.05 mW at 3 V, and wirelessly reconstructs an 800 μV neural spike over a distance of ∼13 cm with an I/O correlation coefficient of ∼96%.
