We present a simple circuit that performs Fermi-Dirac integration. The core of the circuit is a differential amplifier that we show is a model of a Fermi-Dirac system. The construction and characterization of the circuit requires students to apply knowledge of device physics, transistor circuit theory, and signal processing. The circuit construction is relatively simple and requires only a few components found in most electronics laboratories.

The data sheet on the 2N2222a transistor does not give a plot of the versus the collector current, and reports only the minimal for a set of collector currents and fixed collector-emitter voltage.
