Abstract :
A 2.5 MB/s, 400 MHz RF transceiver was design for implantable biomedical micro-stimulators in a 0.18 mum CMOS process. It consists of a transmitter with an output power of -4.5 dBm and a receiver that can detect input signal at < -95 dBm. When one time slot of 6us in a -llrns data frame is used, the transceiver has an effective bit rate of 1.36 kB/s, and consumes ~23 muA for receive and ~8 muA for transmit from a 3.6 V battery. The total number of stimulators that the system can support is 852.
