Propagation delay (t
signal. Propagation delay is attributed to inductive loading within the linear IC package, as well as in the induc-
tive loop formed by the primary conductor geometry. Propagation delay can be considered as a fi xed time offset
and may be compensated.
Response time (t

Rise time (t
it reaches 90% of its full scale value. The rise time to a step response is used to derive the bandwidth of the
current sensor, in which ƒ(–3 dB) = 0.35 / t
losses observed in the conductive IC ground plane and, to varying degrees, in the ferrous fl ux concentrator
within the current sensor package.
