Summary: | A novel noncoherent BPSK demodulator is presented for inductively powered biomedical devices. Differential Manchester encoding technique is used and data demodulation is based on pulse width measurement method. In addition to ultra low power consumption, high data rate without increasing the carrier frequency is achieved with the outstanding data-rate-to-carrier-frequency ratio of 100%. The proposed demodulator is especially appropriate for biomedical applications where high speed data transfer is required, e.g., cochlear implants and visual prostheses. The circuit is designed in a 0.18-mum standard CMOS technology and consumes as low as 232 muW @1.8 V at a data rate of 10 Mbps. |
