  • Patent number: 10972323
    Abstract: In a general aspect, a data communication circuit can include a differential transmitter configured to be coupled with a differential input of a first unidirectional differential isolation channel, and a differential receiver configured to be coupled with a differential output of a second unidirectional differential isolation channel. The differential receiver can include a comparator that has a threshold that is adjustable based on a signal received via the second unidirectional differential isolation channel.

  • Patent number: 10554456
    Abstract: In a general aspect, a data communication circuit can include a transmitter configured to transmit a first digital bit stream via a first unidirectional isolation channel. The data communication circuit can further include a receiver configured to receive a second digital bit stream via a second unidirectional isolation channel. The first unidirectional isolation channel and the second unidirectional isolation channel can be defined on a common dielectric substrate. The data communication circuit can further include a crosstalk suppression circuit configured to provide at least one negative feedback signal to suppress crosstalk between the transmitter and the receiver due to parasitic capacitive coupling between the first unidirectional isolation channel and the second unidirectional isolation channel in the common dielectric substrate.

  • Patent number: 9197222
    Abstract: Capacitive adjustment in an RCL resonant circuit is typically performed by adjusting a DC voltage being applied to one side of the capacitor. One side of the capacitor is usually connected to either the output node or the gate of a regenerative circuit in an RCL resonant circuit. The capacitance loading the resonant circuit becomes a function of the DC voltage and the AC sinusoidal signal generated by the resonant circuit. By capacitively coupling both nodes of the capacitor, a DC voltage can control the value of the capacitor over the full swing of the output waveform. In addition, instead of the RCL resonant circuit driving a single differential function loading the outputs, each output drives an independent single ended function; thereby providing two simultaneous operations being determined in place of the one differential function.
