Simulation (pSPICE and analytical) of the RC behavior of the output voltage (R
TMR

, C

= 1nF). Voltage step on V
DD
. The 100nF capacitor on V
DD
is not included in the simulations
The transient behavior when applying an AC magnetic field with frequency f is shown in
and
.
The pSPICE simulation is compared with analytical calculations according to
and
below. Again, a good fit is achieved using R = 4k
Ω
for the calculation.
