1. A system comprising:
a current-to-voltage converter to generate differential voltages from differential currents comprising a first current and a second current, the current-to-voltage converter comprising:
a first bitline to provide the first current;
a second bitline to provide the second current;
a first regulator to apply a first voltage to the first bitline;
a second regulator to apply a second voltage to the second bitline;
a regulating circuit comprising a first input terminal, a second input terminal, a first output terminal, and a second output terminal, the first output terminal and the second output terminal providing the differential voltages; and
a common mode circuit comprising a first terminal coupled to the first bitline and the first input terminal of the regulating circuit and a second terminal coupled to the second bitline and the second input terminal of the regulating circuit, wherein the common mode circuit maintains a same voltage on the first terminal and the second terminal.
