Angle sensor with integrated amplifier
10.6 Start-up angle error
The start-up angle error is defined as maximum deviation by calculating the angle from
the offset voltages V
offset(VOUT1)
and V
offset(VOUT2)
and the peak-to-peak signal amplitudes
V
o(VOUT1)
and V
o(VOUT2)
.
Figure 11
and Figure 12 show the maximum start-up angular error related to 180 degree
angular range of the MR sensor after one point calibration at 25 C (from worst case
simulations).
