Abstract: A fully symmetrical and balanced monolithic or multi-die integrated circuit transformer device is described. The device can comprise a first and second transformer. The first and second transformer can each comprise a symmetrical bottom coil including electrically conductive crossovers between individual windings of pairs of adjacent windings. Each of the bottom coils can further comprise a first, a second differential terminal, and a center tap third terminal electrically connected to the inner-most winding of the bottom coil. Each transformer can further comprise a spiral top coil electrically connected to an encompassed inner pad and a laterally offset outer pad, the top coil, inner pad, and outer pad including a shared electrically conductive integrated circuit layer. The respective top coils of each transformer can be overlaid and separated from the respective bottom coils by an electrically insulating dielectric layer.

Abstract: An isolator system has an isolator that generates differential isolator signals and a receiver that generates digital data representative of signals received from the isolator. The system also may include an RC filter coupled between the isolator and the receiver. During operation, the filter may distribute transient signals across various circuit paths in the isolator, only some of which are coupled to the receiver inputs. Over time, the filter may attenuate transient contributions at the receiver inputs. In this manner, the filter may limit effects of these common mode transients.

Abstract: Isolators for signals and/or powers transmitted between two circuits configured to operate at different voltage domains are provided. The isolators may have working voltages, for example, higher than 500 Vrms, higher than 1000 Vrms, or between 333 Vrms and 1800 Vrms. The isolators may have a fully symmetrical configuration. The isolators may include a primary winding coupled to a driver and a secondary winding coupled to a receiver. The primary and secondary windings may be laterally coupled to and galvanically isolated from each other. The primary and secondary windings may include concentric traces. The primary and secondary windings may be fabricated using a single metallization layer on a substrate.

Abstract: A receiver system for an on-off key (“OOK”) isolator system may include a pair of receivers. A first receiver may generate a first current signal representing a received OOK signal, and a second receiver may generate a second current signal from a common mode representation of the received OOK signal. The receiver system may include circuitry to compare the first and second current signals and generate an output signal therefrom.

Abstract: A receiver system for an on-off key (“OOK”) isolator system may include a receiver that generates an intermediate current signal based on an OOK input signal. The intermediate current may be provided at a first current level when the input signal has a first OOK state and a second current level when the input signal has a second OOK state. The system also may include an output driver to generate a voltage representation of the intermediate current signal. Performing signal processing in a current domain permits fast transitions between OOK states.
