The driver circuit includes a voltage source to supply a regulated voltage and a regulator current. A main branch is coupled between the voltage source and the transmission line and includes variable impedance circuitry. The main branch draws a drive current from the voltage source. A compensating branch is coupled to the voltage source in parallel with the main branch and includes a second variable impedance circuit to draw a compensating current from the voltage source based on the drive current, such that a sum of the drive current and the compensating current is substantially constant during the transmission of the input data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable resistor voltage driver with self-noise compensation circuit","description":"A multi-PAM line driver circuit to drive input data along a transmission line from a voltage source is disclosed.
