Wirelessly measured dc characteristics of the system with input current in the range of 500 fA–600 nA. Measured values in each region are normalized to the maximum value of the corresponding region (i.e., 600 nA, 150 nA, 37 nA, 5 nA for regions A, B, C, and D, respectively). High linearity is achieved over six decades of the input current.
