Product Number: ADALM2000
Question 1:
How will the response of the circuit change if the value of the inductor is changed?
Answer 1:
Because the strength of the magnetic field is proportional with the value of the inductance, choosing an inductor with value bigger than 100uH will result in a higher voltage at the output of the sensor when the electromagnetic is closer to the chip. If the inductor has a smaller value, the effect will be opposite.
Question 2:
Why do we want to lower the output offset voltage?
Answer 2:
By lowering the offset voltage, we will implement a ratiometric offset that places the Zero Gauss point at the desired potential.
