Fig. 5: Results of the closed-loop experiment.
From: Single-electron detection utilizing coupled nonlinear microresonators
All tests are processed with the same conditions, i.e., VAC = 316.2 mV and VDC = 18 V. a Detected step response of R1 for a varying coupling voltage. The symbols represent the experimental data of the response frequency from the LIA, and the solid line denotes the mean value in one test. b Allan deviation of oscillator R1. c Measured noise floor of oscillator R1 in one test
