摘要

采用1.2V 0.13 μ m CMOS工艺实现了一种具有3-5 GHz超宽带应用的电流模式滤波器的抗干扰接收器。该芯片的最大电压增益为70db，动态范围为60db。在最大增益模式下，测量到的带内OIP3为+9.39 dBm，带外IIP3为-15 dBm，噪声系数为6.8 dB。给出了一种自动数字直流偏置校正算法。

A 1.2V interference-sturdiness, DC-offset calibrated CMOS receiver utilizing a current-mode filter for UWB

An interference-sturdiness receiver with a current-mode filter for 3-5 GHz UWB applications is implemented in a 1.2V 0.13 mum CMOS process. The chip provides a maximum voltage gain of 70 dB and a dynamic range of 60 dB. The measured in-band OIP3 is +9.39 dBm, out-of-band IIP3 -15 dBm and noise figure 6.8 dB in the maximum gain mode. An algorithm for the automatic digital DC offset calibration is also demonstrated.
