摘要

相位检波器是锁相环、合成稳定的微波和毫米波频率以及测量相位噪声所必需的。我们提出了一种围绕自采样非线性传输线瞬态发生器集成电路构建的鉴相器装置，该电路以高相位灵敏度交换捕获范围，在9 GHz下观察4.4 V/rad。通过减小片上衰减并充分利用片上采样器的全量程，可以使该鉴相常数加倍。

Enhanced phase detector using nonlinear transmission lines

Phase detectors are essential for phase-locked loops, synthesizing stable micro- and millimeter-wave frequencies, and measuring phase noise. We present a phase detector setup built around a self-sampling nonlinear transmission line transient generator integrated circuit that trades capture range for high phase sensitivity, observing 4.4 V/rad at 9 GHz. This phase detector constant could be doubled by trivially reducing the on-chip attenuation and utilizing the full range of the on-chip sampler.
