A low power inductive-coupled transceiver for inter-chip communication

A novel low power 1-Gbps inductive-coupled transceiver in 0.18 mum CMOS technology is presented in this paper. It consists of a transmitter section which consumes 0.74 mW power and can operate upto 4 Gbps with pulse width of less than 250 ps. The transmitter generates current pulse through inductor both for positive as well as negative transitions of the input signal. The front-end of the receiver is designed using cascaded inverter stages for amplification. The further stages of the receiver consists of differential amplifier, a Schmitt trigger and T-flipflop which gives the final digital output. The transceiver consumes 1.77 mW power for 1-Gbps data rate.
