Figure 3

Plot of experimental (red) tuning curve obtained for our battery-as-coil circuit along with a tuning curve calculated using the model circuit of Fig. 2b (blue) and the equations described in the Supporting Information. The loaded Q, as determined by the width of the tuning minimum was 29. The parameters used in the calculation were: L′ = 0.42 μH, R′ = 25 k\(\Omega\), C1 = C2 = 40 pF, Cm = 0.74 pF, Ct = 0.63 pF.
