Abstract
A circuit for single ended to differential conversion is disclosed. The circuit comprises a source for providing a single ended signal; and a transformer for receiving the single ended signal. The transformer includes first and second inductors. The first and second inductors are mutually coupled. When the operating frequency changes, a phase difference of currents flowing through the inductors changes, and therefore a phase difference between effective impedance of the first and second inductors changes to maintain a substantially 180 degree phase difference due to the mutual coupling.
