Definitions of Dynamic Response Characteristics
Response time (t
a) when the primary current signal reaches 90% of its final
value, and b) when the sensor reaches 90% of its output
corresponding to the applied current.
Rise time (t
reaches 10% of its full scale value, and b) when 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
current losses observed in the conductive IC ground plane.
Propagation delay (t
output to reflect a change in the primary current signal. Propaga-
tion delay is attributed to inductive loading within the linear IC
package, as well as in the inductive loop formed by the primary
conductor geometry. Propagation delay can be considered as a
fixed time offset and may be compensated.
