中文摘要	a group of prototype integrated circuits are presented for a wireless neural recording micro-system. an inductive link was built for transcutaneous wireless power transfer and data transmission. power and data were transmitted by a pair of coils on a same carrier frequency. the integrated receiver circuitry was composed of a full-wave bridge rectifier, a voltage regulator, a date recovery circuit, a clock recovery circuit and a power detector. the amplifiers were designed with a limited bandwidth for neural signals acquisition. an integrated fm transmitter was used to transmit the extracted neural signals to external equipments. 16.5 mw power and 50 bps - 2.5 kbps command data can be received over 1 mhz carrier within 10 mm. the total gain of 60 db was obtained by the preamplifier and a main amplifier at 0.95hz - 13.41 khz with 0.215 mw power dissipation. the power consumption of the 100 mhz ask transmitter is 0.374 mw. all the integrated circuits operated under a 3.3 v power supply except the voltage regulator.
