Abstract

A self-healing mm-wave amplifier using digital controlled artificial dielectric (DiCAD) transmission lines is proposed. DiCAD transmission lines are employed to correct the frequency shifting of input matching (S11), output matching (S22) and gain (S21) due to process, voltage and temperature (PVT) variation and model inaccuracy. On-chip power detector is integrated into the amplifier to detect the output voltage strength, which could be used to implement the closed-loop frequency self-calibration. The chip is implemented in 65nm CMOS with a die area of 0.48×0.79 mm2 including the PADs. Measurement results show that the gain of the amplifier is improved by 3.4dB and the input matching is improved by 20.3dB at 56GHz after healing.

一种采用数字控制人工介质传输线的自愈毫米波放大器

提出了一种采用数字控制人工介质(DiCAD)传输线的自愈毫米波放大器。DiCAD传输线用于校正由于工艺、电压和温度(PVT)变化和模型不准确导致的输入匹配(S11)、输出匹配(S22)和增益(S21)的频移。放大器中集成了片上功率检测器，用于检测输出电压强度，实现闭环频率自校准。该芯片采用65nm CMOS实现，包括pad在内的芯片面积为0.48×0.79 mm2。测量结果表明，修复后放大器的增益提高了3.4dB，输入匹配度提高了20.3dB。
