Bruker MRI CryoProbe with MRI cryocooler increases sensitivity of in-vivo probes by factors of 2.5 to 5.3 compared to standard room temperature RF-coils. Bruker’s MRI CryoProbe uses cryogenic RF ...

this is very much an RF chip with elaborate control over the profile and amplitude of output pulses. Intel chose a 22nm finfet process on which to build it. There were three other cryo-CMOS papers, ...
