An Inductive-coupling Link with a Complementary Switching Transmitter and an Integrating Receiver

A transceiver for a high-speed inductive-coupling link is proposed. The bi-phase modulation (BPM) signaling scheme is used due to its good noise immunity. The transmitter utilizes a complementary switching method to remove glitches in transmitted data. To increase the timing margin on the receiver side, an integrating receiver with a pre-charging equalizer is employed. The proposed transceiver was implemented via a 130-nm CMOS process. The measured timing window for a 10-12 bit error rate (BER) at 1.8 Gb/s was 0.33 UI.
