AbstractThe design and characterization results of a high-resolution phase-shifter are presented. The phase-shifter is designed with radiation hardening techniques and fabricated in 65~nm CMOS technology. The phase-shifter circuit can produce several output frequencies (40, 80, 160, 320, 640 or 1280~MHz) with an adjustable phase (48.4~ps resolution). It has been fully characterized displaying INL$<$0.61~LSB and DNL$<$0.44~LSB with the power consumption, depending on the output frequency, staying below 8~$\mu$W/MHz.
