Common mode transient immunity for an isolation system is improved by using a common transient suppression circuit coupled to a receive circuit to suppress transients in signals received by the receive circuit that were transmitted from a transmit side of the isolation barrier using optical, magnetic, inductive, or other mechanisms.

Suppression of transients in communications across an isolation barrier

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.

Isolated serializer-deserializer

One embodiment of an apparatus for switching a transistor includes a first current mirror providing i=Ki, as a transistor base current, wherein the first current mirror is selectively driven by a current source A second current mirror providing a feedback signal i=Kito the first current mirror such that wherein icontributes to the transistor collector current, wherein i=i&#x2212;KKi.
