A Fully Integrated CMOS Complex Filter for IEEE802.15.4 Standard

摘要

摘要: 复数滤波器是低中频结构接收机中的一个重要模块，起到镜像抑制的作用。该文针对IEEE802.15.4的低功耗要求，提出了一种可以灵活配置共模反馈模块的伪差分结构OTA，该OTA具有内部共模前馈和共模检测功能，适用于级联应用。基于该OTA结构实现了一个3阶巴特沃斯Gm-C复数滤波器，中心频率在1 MHz，带宽1.3 MHz，带内群延时波动小于0.16 s，镜像抑制能力满足IEEE802.15.4协议要求。该文还提出了一种频率调节方法，用于控制复数滤波器的中心频率，与传统的锁相环结构相比，该调谐电路结构简单，适合在低功耗应用场合。

Abstract: Complex filter is one of the major parts in low-if receiver to reject imagine signal. Considering the low-power requirement of IEEE802.15.4 standard, this paper presents a pseudo OTA with flexible configuration of common mode feedback block, which is suitable to use in cascade systems for its inner common mode feed-forward and common mode detection. A third-order Butterworth Gm-C complex filter is designed based on this OTA, its center frequency locate at 1 MHz, with a 1.3 MHz bandwidth, the in-band group delay ripple is less than 0.16 s, its IRR(Imagine Rejection Ratio) can satisfy IEEE802.15.4 standards requirements. A frequency tuning method is also presented in this paper, it is simple and power efficiency comparing to traditional PLL tuning method.
