Abstract
A negative impedance circuit including: a first and a second bipolar transistors having a common collector, a base of the first transistor being connected to an emitter of the second transistor; a third and a fourth bipolar transistors having a common collector, a base of the third transistor being connected with an emitter of the fourth transistor; and at least one first impedance formed of one or of a plurality of passive components coupling the common collector of the first and second transistors to the common collector of the third and fourth transistors, a base of the second transistor being coupled to the collector of the third and fourth transistors and a base of the fourth transistor being coupled to the collector of the first and second transistors.
