2results about "Broad-band transformers" patented technology

A digital isolator can include: a first die having one of an encoding circuit and a decoding circuit; a second die having one of the encoding circuit and the decoding circuit that is not in the first die, where the first die and the second die are separated from each other; and an isolated transmission structure configured to transmit an encoded signal generated by the encoding circuit to the decoding circuit.

The invention discloses an on-chip transformer and an electronic device, and relates to the technical field of semiconductors, and the disclosed on-chip transformer comprises a primary coil, a secondary coil and a metal wire; the primary coil is a coil for receiving a direct current signal, and the secondary coil is a coil which does not receive the direct current signal; the primary coil and the secondary coil are isolated from each other and are arranged in a staggered mode through metal wires. The coil width of the primary coil is greater than the coil width of the secondary coil. The coil width of the primary coil is set to be larger than the coil width of the secondary coil, so that the overall area is not obviously increased on the basis of ensuring a high quality factor and reducing signal transmission loss, and miniaturization design of a chip is facilitated.
