All tests are processed with the same conditions, i.e., VAC = 316.2 mV and VDC = 18 V. a Peak frequency fP of the amplitude-frequency curves of R1 for different coupling voltages. The inset shows the amplitude-frequency curves for a coupling voltage below the threshold (blue dashed line) and above the threshold (red solid line). b Measured responses of R1 for VC values ranging from 5 V to 16 V with a 1 V step. c Measured peak frequency of R1 shifts vs the coupling voltage. d Measured responses of R1 for VC values ranging from 14.50 V to 14.55 V with a 0.01 V step
