    Abstract: A first integrated circuit die receives input data from a plurality of input channels and combines the input data from the plurality of input channels into combined data. The first integrated circuit die transmits the combined data across an isolation communication channel. A second integrated circuit die that is coupled to the isolation communication channel decodes the transmitted combined data and supplies the decoded transmitted combined data to respective output channels corresponding to the input channels.

    Abstract: A method includes supplying a current to at least one conductive path integral with a MEMS device to thereby exert a Lorentz force on the MEMS device in the presence of a magnetic field. The method includes determining the magnetic field based on a control value in a control loop configured to maintain a constrained range of motion of the MEMS device. The control loop may be configured to maintain the MEMS device in a stationary position. The current may have a frequency equal to a resonant frequency of the MEMS device.

    Abstract: An apparatus for communicating using an isolation channel includes a transmitter circuit having a first terminal configured to communicate a first signal. The first signal oscillates in response to a data signal having a first signal level and is constant in response to the data signal having a second signal level. The transmitter circuit includes a second terminal configured to communicate that oscillates in response to the data signal having the second signal level and is constant in response to the data signal having the first signal level. The apparatus may include a receiver circuit configured to generate a recovered data signal having a first transition in a first direction between first and second levels based on an edge of a first received signal and having a second transition in a second direction between the first and second levels based on an edge of a second received signal.
