摘要

提出了一种用于高速片间数据通信的宽带120ghz上转换混频器，采用40nm CMOS工艺。在混频器的跨导级采用负反馈电阻和PMOS晶体管，提高了转换增益和带宽。根据测量结果，该混频器在低本振(LO)驱动功率为-4 dbm时，最大转换增益为- 3.5 dB, 3db带宽为26 ghz。在0.9 v供电电压下，功耗仅为8mw。

A Wideband 120 GHz Up-Conversion Mixer in 40 nm CMOS for Chip to Chip Communication

A wideband 120-GHz up-conversion mixer for high-speed chip to chip data communication is presented in a 40 nm CMOS process. Using a negative feedback resistor and PMOS transistor at transconductance stage of mixer, the conversion gain and bandwidth are both enhanced. According to the measurement results, the proposed mixer achieves a maximum conversion gain of −3.5 dB and a 3-dB bandwidth of 26-GHz at low local oscillator (LO) drive power of -4-dBm. The power consumption is only 8-mW at 0.9-V supply voltage.
