摘要： The invention provides a current balancing circuit for powering a first load with a negative dynamic resistance and a second load with an essentially different negative dynamic resistance, and a transformer with such turns ratio that at least at an operating frequency impedances of the first and second windings complement the resistances of the first and the second loads, respectively, to a common value.
