Dual diode-based current sense system: Uncertainty sources and possible accuracy improvements

Resistors are the classical current sense device; nevertheless, they are range-limited due to power constrains. A diode, given its exponential I(V) function, potentially offers wider range of current measurements than a resistor. To investigate the feasibility of a diode-based current sense device, the Texas Tech-Teradyne Diode Project phase 1 developed a proof-of-concept system based on a dual diode package. This thesis describes how that system was implemented, identifying sources of uncertainty from calculations and measurements, and suggesting posterior corrections to model outputs based on calibration.
