The result of electrophysiological experiment reveals more realistic and integrated information while animals under testing are awake. For continuous and simultaneous multichannel wireless recording of action potentials, low-power and high data bandwidth are the most critical issues. A 400 MHz wireless recording system with 3 Mb/s data rate is presented in this paper. The front-end transmit module, including amplifiers and filters, draws 12 mA from a 3.7 V supply. To verify the system, a receive module with user interface is built specifically for the high data rate transmission. Reconstructed waveform from the receive module are 98.86% similar to the traditional wiring measurement.
