摘要

近年来,采用多级正交调幅(QAM)的无线设备越来越多,因此需要由低成本CMOS电路组成的高精度正交调制器。本文首先描述了一种双本振(LO)开关正交混频器或调制器的结构,从而实现了高调制精度。它具有对正交(I/Q) LO信号相位误差的补偿机制。该技术可应用于数字调制/解调和边带或图像信号抑制的频率转换过程。接下来,我们提出了一种高精度正交调制器,结合了双lo开关技术和新提出的适用于现代RF收发器的全差分CMOS触发器移相器。

A High-Precision Quadrature Modulator Using a Fully-Differential CMOS Flip-Flop Phase-Shifter Suitable for the Next-Generation RF Transceivers
In recent years, the number of wireless devices that use multi-level quadrature amplitude modulation (QAM) is increased, thereby requiring high-precision quadrature modulators composed of low-cost CMOS circuits. This paper first describes an architecture of a dual-local-oscillator (LO) switching quadrature mixer or modulator, thereby enabling high modulation accuracies. It features the compensation mechanism of phase errors of quadrature (I/Q) LO signals. This technique can be applied to digital modulation/demodulation and sideband or image-signal rejection in frequency conversion processes. Next, we propose a high-precision quadrature modulator, combining the dual-LO switching technique and a newly-proposed fully-differential CMOS flip-flop phase-shifter suitable for modern RF transceivers using multi-level QAM.
