Abstract

A highly-integrated 211 -1 pseudo-random bit sequence (PRBS) transmitter for biomedical applications is presented. The chip consists of an ultra-wideband synthesizer with an integrated divider to drive a PLL, a linear feedback shift register (LFSR) to generate an M-sequence and a programmable binary divider to enable adaptive subsampling technique in the signal processing path. The circuit is created to be used in a miniaturized portable PRBS based sensor system for biomedical applications. A conceivable application is the measurement of dehydration in a human body. The PRBS generator is capable of generating a bit-rate up to 10Gb/s, correlating to a maximum bandwidth of the generated sequence of 5GHz, which is sufficient for the designated applications. The circuit is manufactured in an 0.35 μm SiGe-Bipolar technology with an ft of 200GHz using 12mm2 chip area.
