非福斯特电路的成功设计需要精确可靠的稳定性测试。环路增益和Llewellyn或Rollett测试已被用作非福斯特电路稳定性分析的基础。然而，这些测试是不可靠的，可能会报告一个非福斯特电路是稳定的，当它不是。给出了一些简单的电路，作为这种测试的反例。因此，回路增益和卢埃林-罗利特测试不应该依赖于评估非福斯特电路的稳定性。使用这些测试得出的任何电路稳定性证明都不应被接受。
The successful design of non-Foster circuits requires tests for stability that are accurate and reliable. The loop-gain and Llewellyn or Rollett tests have been used as the basis for stability analyses in papers on non-Foster circuits. However, these tests are unreliable and can report that a non-Foster circuit as stable when it is not. Simple circuits are shown that serve as counter examples to such tests. Consequently, loop-gain and Llewellyn-Rollett tests should not be relied on for evaluating the stability of non-Foster circuits. Any demonstration of circuit stability from the use of these tests should not be accepted.
