Abstract: A measurement circuit comprises an input terminal to receive a current signal, a first circuit branch coupled to the first terminal and including one or more circuit elements to receive a portion of the current signal, a second circuit branch coupled to the first terminal and including one or more additional circuit elements to receive another portion of the current signal, a nonlinear circuit element coupling the first circuit branch to the second circuit branch, and a quantization circuit configured to produce an input current measurement of current in the first and second circuit branches, and to include current in the second circuit branch in the input current measurement according to a magnitude of the input current signal.
