Digital isolator architecture for hybrid capacitor and inductor

An apparatus comprising:

• a receiver comprising a receiver inductor-capacitor (LC) tank and a differential receive amplifier;
• a transmitter comprising an oscillator and a differential transmit driver;
• and
• a capacitive isolation barrier electrically coupled between an output of the transmitter and an input of the receiver,
• wherein:
• the oscillator is electrically coupled to a first input of the differential transmit driver by a first capacitor;
• the oscillator is electrically coupled to a second input of the differential transmit driver by a second capacitor;
• the receiver LC tank comprises a coupled inductor pair having a center tap and one or more capacitors, the coupled inductor pair being electrically coupled between differential inputs of the differential receive amplifier;
• and
• the coupled inductor pair is configured to cancel a common mode transient signal passing through the receiver LC tank without attenuating a differential signal of interest at a resonant frequency of the receiver LC tank.
