Integrated control unit for wireless recording of brain activity

Multichannel integrated recording systems are the gate for our understanding of mammalian brain activity. For in vivo neurobiological brain experiment on animals moving free with the wireless control and data transmission it is necessary to eliminate the tethering effect and not to limit animals movement. We have designed in CMOS 180nm technology and sent to fabrication an ASIC that is a Control Unit for wireless recording of brain activity. The Control Unit is designed for a System on Chip which will consists of signal conditioning channels, analogue multiplexer, A/D converter and RF transmitter. The task of the Control Unit is management of data acquisition and wireless transmission.
