Abstract:
1. A circuit comprising: at least one transistor comprising: a first transistor and a second transistor, each of the first transistor and the second transistor having a base, a collector, and an emitter; at least one current source being configured to apply four different currents (A, B, C, and D) to the emitter of the at least one transistor, the at least one current source being configured to produce the four different currents with either: a sum of the current A and the current C being substantially equivalent to a sum of the current B and the current D; or a sum of the current A and the current D being substantially equivalent to a sum of the current B and the current C; and the circuit being configured to output: the first transistor and the second transistor being configured to:
