Abstract:
A highly integrated chipset for wearable wireless body sound sensor is presented. It consists of a body sound sensor readout chip and a 400M-440MHz short range wireless transceiver chip. The sensor readout chip consists of a programmable preamplifier and an over-sampling ADC, and it consumes no more than 80μA current from 1.2V power supply. In the transceiver chip, the transmitter adopts a direct up-conversion architecture and delivers +6dBm maximum output power. The receiver employs zero-IF architecture, and it achieves a sensitivity of -93dBm @ 1Mbps MSK modulation. A body sound sensor prototype has been implemented using this chipset.
