    Abstract

    This paper presents a pulse-based inductive-coupling transceiver with adaptive pulse width controller for high-speed wireless proximity communication. Adaptive pulse width controller uses 20 phase clocks generated by a multi-phase digitally-controlled-array-oscillator and prevents the pulse width fluctuation under PVT variation at ultra-low power supply voltage. Pulse generation and its width detection are carried out by the identical multi-phase oscillator, which reduces the circuit area. The test chip implemented in 65nm-CMOS has achieved data rate of 850Mb/s/ch at 0.7V supply voltage and power consumption of 4.1mW.
