摘要

本文提出了一种低功率有源rc滤波器，具有可重构传递函数，3 /5阶巴特沃斯，集成在低中频GPS接收机中，采用0.35um SiGe BiCMOS技术制造。这个17/26 dB增益滤波器的带宽为2.6MHz，其中心为4.1MHz。它在3 /5阶模式下从2.7V电源消耗1/1.25mA。该0.58 mm2滤波器的平均带内图像抑制优于25dB。此修剪滤波器采用正交偏移抵消电路，以消除来自混频器输出和自身不匹配的所有可用偏移。

A 2.6 MHz Bandwidth, 3rd/5th Order Active-RC Polyphase Filter with Quadrature Offset Cancellation for Low-IF GPS Radio

In this paper a low power active-RC filter exhibiting a reconfigurable transfer function, 3rd/5th order Butterworth, integrated in a low IF GPS receiver and fabricated in 0.35um SiGe BiCMOS technology is presented. This 17/26 dB gain filter has a bandwidth of 2.6MHz which is centered at 4.1MHz. It drains 1/1.25mA from a 2.7V supply in 3rd/5th order modes. The average in-band image rejection of this 0.58 mm2 filter is better than 25dB. This trimmed filter employs a quadrature offset cancellation circuit to remove all the available offset coming from the mixer output and its own mismatches.
