本文提出了一种基模压控振荡器(VCO),采用130 nm SiGe BiCMOS工艺实现,工作频率可达200 GHz。实现的拓扑结构源自反馈移相器设计,其包括基于90°和180°传输线耦合器的宽带无源多相滤波器和可变增益有源组合器。所制作的电路实现了173-200 GHz的非常大的频率调谐范围,在188 GHz附近的10 MHz偏移处相位噪声低至− 85 dBc/Hz。作为一项独特功能,该拓扑允许同时生成90°正交信号,这些信号由附加的单级输出缓冲器放大。两个输出信号在宽带宽上的功率电平均为−3 dBm,振荡器内核的总直流功耗为27.7 mW,每个缓冲器的总直流功耗为10.3 mW。
This work presents a fundamental-mode voltage-controlled oscillator (VCO) realized in a 130 nm SiGe BiCMOS process for operation up to 200 GHz. The implemented topology is derived from a feedback phase shifter design, which includes a wideband passive polyphase filter based on 90° and 180° transmission line couplers and a variable-gain active combiner. The fabricated circuit achieves a very large frequency tuning range of 173–200 GHz with a phase noise down to −85dBc/Hz at 10 MHz offset around 188 GHz. As an unique feature this topology allows the simultaneous generation of 90° quadrature signals, which are amplified by an additional single-stage output buffer. The power level of both output signals over a wide bandwidth is −3 dBm each, with a total dc power consumption of 27.7 mW for the oscillator core and 10.3 mW per buffer.
