Due to the high inner resistance of the printed G-CAPode (≈ 700 Ω) the maximal output voltage at 100 kHz is very low amounting to only 1.8 mV. Using a higher resistance, however, would drastically shift fC to very low frequencies according to Equation 1 at which no or only a minimal phase shift difference of positive and negative Ubias could be observed. According to the results in Figure , fC,+,exp and fC,-,exp experimentally achieved reach 225 and 1178 Hz which is in excellent agreement with the values predicted by calculation.
