Abstract

Research in recent years has demonstrated that intra and inter-chip wireless interconnects are capable of establishing energy-efficient data communications within as well as between multiple chips. This paper presents a circuit level design of an energy-efficient millimeter wave (mm-wave) on-off keying (OOK) transmitter suitable for such wireless interconnects in 45-nm CMOS process. The transmitter consists of an NMOS cross-coupled VCO, an OOK modulator and a power amplifier. The transmitter is able to achieve maximum modulation data rate of 16Gb/s at 60GHz with the output power of -3dBm consuming a total power of 3.9mW, which translates to a bit-energy efficiency of 0.24pJ/bit.
一种0.24pJ/bit, 16Gbps的45纳米CMOS OOK发送电路,用于片内和片间无线互连
近年来的研究表明,芯片内和芯片间的无线互连能够在多个芯片内部和芯片之间建立节能的数据通信。本文提出了一种适用于45纳米CMOS工艺无线互连的毫米波开关键控(OOK)发射机的电路级设计。该发射机由NMOS交叉耦合VCO、OOK调制器和功率放大器组成。该发射机在60GHz时能够实现16Gb/s的最大调制数据速率,输出功率为-3dBm,消耗的总功率为3.9mW,转换为0.24pJ/bit的位能效率。
