Abstract :
Low-power interface circuits used in wireless bio-implantable microsystems are described. Regulators have line regulation of 3mV/V, load regulation of 8mV/mA, and ripple rejection of 45dB. An ASK demodulator achieves a bit rate of 60kb/s, and the frequency of the recovered clock reaches 10MHz. An on-chip active transmitter achieves a bit rate of 2Mb/s. Total power dissipation is 2.17mW for a 4.84mm/sup 2/ IC fabricated in 0.8/spl mu/m CMOS.
