摘要/Abstract

摘要： 为满足宽频带、高性能的要求，设计了一款V波段毫米波宽带数控振荡器（DCO）。采用基于互感开关变压器的电感调谐技术，通过互感开关控制一组耦合变压器实现双模切换，输出低频子带或高频子带，从而实现宽带设计。采用离散电压控制可变电容器实现离散电容器调谐，与开关电容相比降低了寄生电容和损耗，能够实现更大的带宽和良好的相位噪声。电路基于40nm CMOS工艺设计，核心芯片面积仅为0.053 mm²。频率调谐范围为57.85~72.30 GHz，1 MHz频偏处相位噪声范围为－95.32~－91.07 dBc/Hz。

Abstract: A V-band millimeter-wave broadband digitally controlled oscillator (DCO) is designed to meet the wideband and high-performance requirements. The inductive tuning technique based on mutual inductance switching transformers is used to achieve a broadband design by controlling a set of coupling transformers through mutual inductance switching to realize dual-mode switching and output low-frequency sub-bands or high-frequency sub-bands. The discrete capacitor tuning is achieved by using a discrete voltage controlled variable capacitor, which reduces the parasitic capacitance and loss compared to the switched capacitor, enabling a larger bandwidth and good phase noise. The circuit is designed based on a 40 nm CMOS process with a core chip area of only 0.053 mm². The frequency tuning range is 57.85-72.30 GHz, and the phase noise range is －95.32-－91.07 dBc/Hz at 1 MHz frequency bias.

Key words: millimeter-wave, digitally controlled oscillator, broadband, mutual inductance switching transformer
