AB  - This  paper  describes  an  integrated  communicationsystem, implementing a UWB-inspired pulsed coding technique,for  an  optical  transcutaneous  biotelemetry.  The  system  consistsof  both  a  transmitter  and  a  receiver  facilitating  a  bidirectionallink. The transmitter includes a digital data coding circuit and iscapable of generating sub-nanosecond current pulses and directlydriving  an  off-chip  semiconductor  laser  diode  including  all  biasand  drive  circuits.  The  receiver  includes  an  integrated  compactPN-junction  photodiode  together  with  signal  conditioning,  de-tection  and  digital  data  decoding  circuits  to  enable  a  high  bitrate, energy efficient communication. The proposed solution hasbeen  implemented  in  a  commercially  available  0.35μm  CMOStechnology provided by AMS. The circuit core occupies a compactsilicon  footprint  of  less  than  0.13 mm2(only  113  transistors  and1  resistor).  Post-layout  simulations  have  validated  the  overallsystem operation demonstrating the ability to operate at bit ratesup  to  500 Mbps  with  pulse  widths  of  300 ps  with  a  total  powerefficiency  (transmitter  +  receiver)  lower  than  74 pJ/bit.  Thismakes the system ideally suited for demanding applications thatrequire  high  bit  rates  at  extremely  low  energy  levels.  One  suchapplication  is  implantable  brain  machine  interfaces  requiringhigh uplink bitrates to transmit recorded data externally througha  transcutaneous  communication  channel.
