Abstract
An integrated circuit comprises a current source, a plurality of parallel transistors, a plurality of switches, switch control circuitry, and measurement circuitry. Each switch selectively couples the current source to a corresponding transistor. The switch control circuitry is configured to, at different times, cause all the switches to close and, separately for each transistor, cause the switch associated with each transistor to close while causing all other switches to open. The measurement circuitry is configured to measure, separately for each of the transistors, a base-emitter voltage (VBE) when all the switches are closed and a VBE when only the switch associated with each transistor is closed, determine a ΔVBE for each of the plurality of transistors by calculating a difference between the VBE when only the switch associated with each transistor is closed and the VBE when all the switches are closed, and calculate an average of all the ΔVBEs.
