Patent number: 10554456Abstract: 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.Type: GrantFiled: August 14, 2018Date of Patent: February 4, 2020Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Syed Enam Rehman, John Constantino

Patent number: 9197222Abstract: 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.Type: GrantFiled: December 16, 2013Date of Patent: November 24, 2015Assignee: Tensorcom, Inc.Inventor: Syed Enam Rehman
