Abstract

A low power, unidirectional, user-adjustable wireless interface for back telemetry of biological data in reliable multichannel wireless systems is designed and fabricated in 2P3M, 0.5μm standard CMOS process. The RF blocks operate in the ISM band of 433MHz. The power consumption and transmission range of this wireless interface is user adjustable through 4-bits. The wireless multichannel neural recording transmitter employing the presented RF transmitter has shown a measured transmission range of 20m with a total input referred voltage noise of less than 9μV_rms.
