摘　　要：基于90 nm CMOS工艺制作了一种K波段高性能五倍频器。该五倍频器电路由正交再生分频器、单平衡混频器和三倍频器级联组成。使用电流可再生技术设计了正交再生分频器,有效降低了系统的整体功耗,使用吉尔伯特混频器电路结构提高了转换增益。整体电路具有正交输入/输出、输出功率高、谐波抑制度高的优点。测试结果表明,该五倍频器的-3 dB频率范围为24~26.2 GHz,在输入功率为3.9 dBm时,转换增益为-3.34 dB。输出信号的最大相位误差为2.398°,直流功耗为14.83 mW,芯片面积约为0.99 mm^(2)。A K-band high performance frequency quintupler was fabricated with 90 nm CMOS process.The quintupler circuit consists of a quadrature regenerative frequency divider,a single-balanced mixer and a tripler in a cascaded structure.The overall power consumption of the system was effectively reduced by the current-reused technology to design the quadrature regenerative frequency divider,and the conversion gain was improved by using the Gilbert mixer circuit structure.The whole circuit has the advantages of quadrature input/output,high output power and high harmonic suppression.The measured results show that the frequency quintupler has a-3 dB frequency range of 24-26.2 GHz and a conversion gain of-3.34 dB at an input power of 3.9 dBm.The maximum phase error of the output signal is 2.398°,the DC power consumption is 14.83 mW and the chip area is about 0.99 mm^(2).
