In high-impedance current-input inverting configurations, where a length of shielded wire is used to guard the lead from the current source to the amplifier's inverting input, the guard should either be driven by a buffer at the same potential as the non-inverting input, or be tied directly to the non-inverting input, with a second outer shield connected to the signal's reference point.

如果将运放接成反相放大器的形式，并且在信号源与运放反相端之间用一段带有屏蔽层的导线来充当的防护罩，那么对防护罩的处理有两种选择：要么用一个缓冲跟随器来驱动，跟随器输出端与运放同相端电位相等，而且除跟随器外，防护罩不与其他点接触；要么将防护罩直接接到运放的同相端，然后在其外面加一个屏蔽层，并且将屏蔽层连接到信号的参考电位。
