Abstract
An integrated circuit comprises a current source, a plurality of transistors arranged in parallel, a plurality of resistors, a plurality of switches, switch control circuitry, and measurement circuitry. Each resistor is coupled with the emitter of a respective transistor. Each switch selectively couples the current source to a respective resistor such that a bias current flows from the current source to the emitter of a respective transistor when a respective switch is closed. The measurement circuitry is coupled to the first transistor between its emitter and a respective resistor. The measurement circuitry is configured to separately measure a base-emitter voltage (VBE) of the first transistor when all of the switches are closed and a base-emitter voltage (VBE) of the first transistor when only the switch associated with the first transistor is closed and to determine a ΔVBE by calculating a difference between VBEand VBE
