论文摘要
本文提出了使用变压器反馈和电流恢复技术增加频率范围的低功率正交电压控制的振荡器（QVCO）设计。随着芯片应用应用中QVCO的需求不断增长，基于QVCO的常规基于螺旋感应的方法由于其尺寸较大而成为主要的瓶颈。为了解决这一问题，我们建议用三维综合电路（3D IC）中基于硅电感（TSV）电感器的方法替代基于螺旋感应器的方法。此外，与常规设计相比，提出的QVCO电路可以提供更高的操作频率范围。实验结果表明，用TSV变压器代替常规的螺旋变压器，金属资源消耗降低了3.9倍。拟议的QVCO的相位噪声为-114 $ dbc/hz $@1 $ MHz $和-111.2 $ dbc/hz $@1 $ MHz $在2.5 $ ghz $的toroidal TSV转换的基于QVCO和基于垂直螺旋变压器的基于垂直螺旋变压器基于2.5 $ GHz $的运营商。在0.7 $ V $的电源电压下，电动TSV TSV转换的QVCO和基于垂直螺旋变压器的基于TSV转换的QVCO和垂直螺旋变压器的功耗分别为1.5 $ MW $和1.7 $ MW $。
Low-power quadrature voltage-controlled oscillator (QVCO) design utilizing transformer-feedback and current-reuse techniques with increased frequency range is proposed in this paper. With increasing demand for QVCOs in on-chip applications, the conventional spiral inductor based approaches for QVCOs has become a major bottleneck due to their large size. To address this concern, we propose to replace the conventional spiral inductor based approaches with through-silicon-via (TSV) inductor based approach in three-dimensional integrated circuits (3D ICs). In addition, the proposed QVCO circuit can provide higher frequency range of operation compared with conventional designs. Experimental results show by replacing conventional spiral transformers with TSV transformers, up to 3.9x reduction in metal resource consumption. The proposed QVCOs achieves a phase noise of -114 $dBc/Hz$@1 $MHz$ and -111.2 $dBc/Hz$@1 $MHz$ at the carrier of 2.5 $GHz$ for toroidal TSV transformed based-QVCO and vertical spiral transformer based-QVCO respectively. The power consumption is only 1.5 $mW$ and 1.7 $mW$ for toroidal TSV transformed based-QVCO and vertical spiral transformer based-QVCO respectively, under the supply voltage of 0.7 $V$.
