A High-speed Wireless Data Transfer for Non Destructive Testing

초록

This paper presents a sub-THz wireless data transfer (WDT) design for low-power chip-to-chip communication using on-off keying (OOK) modulation scheme. Input baseband data is modulated with a 90-GHz clock signal, which is generated by the proposed near-threshold voltage-controlled oscillator. The modulated signal is transferred through an air media by using the proposed inductive coupler. Since the sub-THz frequency band is utilized, a data rate of 10 Gb/s could be achieved while the chip size is only 0.2 mm(2) and 0.3 mm(2) for transmitter and receiver, respectively. The proposed WDT design consumes only 15 mW power from a 1-V supply.
