Purpose There is a limit to the maximum achievable preamplifier decoupling. In many cases, this level is not enough. To overcome this limit, the preamplifier noise figure can be compromised for further decoupling increase. This is useful in flexible

Cryogenically cooled magnetic resonance imaging (MRI) coils demonstrate extremely high Q -factors, leading to a very narrow bandwidth. This bandwidth can be increased in a controlled manner using a preamplifier decoupling. In this letter, an MRI coil

Shielded loops have recently attracted keen interest in the design of Magnetic Resonance Imaging (MRI) detector arrays. To prevent unwanted detuning of array elements, preamplifier decoupling is used. So far, the decoupling circuit design was based o
