Abstract
A position transducer includes a bias circuit that drives and controls first and second bias coils. The bias circuit monitors the value of a voltage produced in a second sensor coil and drives and controls the first and second bias coils such that the value of the voltage produced in the second sensor coil is always equal to a desired voltage value.
