We present a low power FM transmitter for use in neural recording telemetry. The transmitter
consists of a low noise biopotential amplifier and a voltage controlled oscillator used to
transmit the amplified neural signals at a frequency of 433 MHz. The circuit is powered
through a transcutaneous, inductive link. The power consumption of the transmitter is
measured to be 465/spl mu/W. Using a 1/8-wavelength monopole antenna, a received
power level was measured to be-54.5 dBm at a distance of one meter.
