Abstract
An electronic balun circuit is provided for converting a single-ended signal into a differential signal and vice versa, comprising a center-tapped inductor having a first node, a center-tap coupled to a constant voltage source, and a second node. A first impedance circuit is coupled with the first node and with a line carrying single-ended signal to and from the first node. A second impedance circuit is coupled with the second node. The first node receives the single-ended signal to produce a differential signal at the first and second nodes. The first and second nodes receive the differential signal to produce the single-ended signal at the first node. Both first and second impedance circuits have an impedance of 2R, resulting in a total effective impedance of Rin for achieving an impedance match between the line and the first node. Furthermore, a passive network is added to balance the balun.
