Conversely, a fully differential circuit design works on the principle of a virtual ground where net ground currents sum to zero. For differential circuits the behavior is independent of the ground impedance. Zero current means zero voltage drop and the ground has a single potential level. Evaluating the impedance of a ground path is particularly troublesome. 8. i 50 Ω Lg V 50 Ω V = Lg Signal di dt For small Lg Ground Signal Fig. 8 Direct measurement of ground impedance is a difficult problem; the shunt imperfect short method shown allows a reasonable inference of the equivalent ground inductance.
Conceptually a ground is a common potential reference, independent of the current distribution present in it. In practice a ground plane must be of sufficiently low impedance that the return currents imposed upon it do not impact circuit performance. If this condition cannot be met, then the equipotential requirement of a ground reference is not met. In many applications a ground plane is sufficient as a ground reference. However, high power amplifiers running low-voltage swing and high currents can easily exhibit the effects of non-ideal grounding where different spots on the plane have different potentials.
Bypass capacitor manufacturers often feature their extremely low series resistance, when this is not always an advantage. 2 Non-ideal ground Grounding in circuits has been one of the black arts of analog RF and microwave circuit design . Conceptually a ground is a common potential reference, independent of the current distribution present in it. In practice a ground plane must be of sufficiently low impedance that the return currents imposed upon it do not impact circuit performance. If this condition cannot be met, then the equipotential requirement of a ground reference is not met.
