摘要

综合分析了一种用于内置自检的宽带MOSFET幅度检测器在多种工作条件下的性能。推导了一种用于饱和区域检测的简化rf - dc转换方程。在阈下操作区域中揭示了两种转换模式。第一种模式适用于相对较大的输入信号电平，具有线性rf - dc比例性。第二亚阈值模式，对于小信号电平，具有平方律比例性。研究了饱和区和阈下两种模式下的体效应。对三极管的检测也进行了讨论。介绍了考虑检测器负载对被测电路影响的带宽方程。

Millimeter wave MOSFET amplitude detector

A comprehensive analysis of a wideband MOSFET amplitude detector for Built-In-Self-Test is presented under multiple operating conditions. A simplified RF-to-DC conversion equation for detection in the saturation region is derived. Two conversion modes are uncovered in the subthreshold operation region. The first mode, which applies to relatively large input signal levels, has linear RF-to-DC proportionality. The second subthreshold mode, for small signal levels, has square-law proportionality. The body effect was investigated in the saturation region and subthreshold's two modes. Detection in the triode is also discussed. A bandwidth equation accounting for the detector's loading effects on the circuit-under-test is introduced.
