Abstract
A converter circuit is provided that includes an amplifier circuit and further includes: a summing current resistor that exhibits nonlinear resistance coupled between a voltage node and a summing current node of the amplifier; a compensation resistor circuit includes resistors that exhibit nonlinear resistance; the compensation resistor circuit produces a compensation current at the summing current node that compensates for nonlinear current flow in the summing current resistor.
