Abstract: An isolating Transmission Line Transformer (ITLT) for use in a data communications- system is disclosed. The ITLT comprises a core, a first port for connection to a data source, and a second port for connection to a transmission or data receiver line, said second port being on substantially the opposite side of the core to the first port. In addition, a transmission line is formed by first and second conductors, the first conductor being connected in series to the first port and the second conductor being connected in series to the second port to provide d.c. isolation between the ports. The conductors are arranged side- by-side though or around the core, and each executes a single turn or winding through or around the core.

Abstract: A transformer (100, 180, 500) is described. The transformer comprises a top conductive coil (106, 206, 506), a bottom conductive coil (102), and a dielectric layer (104, 504) separating the top conductive coil from the bottom conductive coil. The top conductive coil comprises an outermost portion (110, 510) having multiple segments (142, 144, 148). The segments are configured to reduce the peak electric field in a region of the dielectric layer near the outer edge of the top conductive coil. The top conductive coil may comprise a first lateral segment (142), and a second lateral segment (144) that is laterally offset with respect to the first lateral segment. The first lateral segment may be closer to the center of the top conductive coil than the second lateral segment, and may be closer to the bottom conductive coil than the second lateral segment. The transformer may be formed using microfabrication techniques.

Abstract: A driver stage, especially for a power switch transistor (210) comprises an auxiliary power supply (202), a current regulator (212) for the base current of the switch transistor and an overdrive, preferably with a logic processor (218). A shell-type transformer (230) having a ferromagnetic core and at least one primary and one secondary coil is used as a switching voltage and power transformer for the positive base current. Its core is as gap-free as possible and at least one coil has the form of a foil. The primary and secondary coils of the transformer are wound on each other, with an intermediate insulating layer, forming cylindrical coils. Each current-conducting part-winding of the primary coil adjoins a current-conducting part-winding of the secondary coil.
