Abstract
A biasing scheme is disclosed that helps reduce current noise in an associated device, such as, for example, a magneto-resistive device. The biasing scheme provides for setting a resistance path in a preamplifier, which is operative to energize the associated device, based on a biasing current that is to be used with associated device. Alternatively or additionally, the resistance path can be set based on a resistance of the associated device. As a result of setting the resistance path in this manner, noise through the associated device can be mitigated during its energization.
