Resonance of the sample circuit in the normal state at T = 450 mK. a Magnitude of Γ(ω) in dB (color scale) as a function of ω and VG. b Magnitude and phase of Γ(ω) at VG = +24 V. c Capacitance CSTO extracted from the resonance frequency \(\omega _0 = 1{\mathrm{/}}\sqrt {L_1C_{{\mathrm{STO}}}}\) (left axis) and normal dc resistance Rn (right axis) as a function of VG. Square symbols indicate the values of VG used for calibration
