Patent ID: 8049537

Claim:
A system for reducing voltage droop in a communication system, the system comprising: a signal source configured to generate a signal, the signal to be transmitted over a communication channel having a characteristic impedance; a voltage driver configured to i) amplify the signal and ii) output the signal on a first signal line and a second signal line; a line isolation device configure to isolate the voltage driver from the channel; a matching resistance configured to match the characteristic impedance, the matching resistance including a first resistor connected in series with the first signal line between i) the voltage driver and ii) the line isolation device, and a second resistor connected in parallel to the first resistor and in series with the second signal line between i) the voltage driver and ii) the line isolation device; and a voltage droop compensator configured to offset low frequency impedance mismatches of the voltage driver and the line isolation device with respect to the characteristic impedance, wherein the voltage droop compensator includes at least one of i) a first capacitor connected in series between the first resistor and the line isolation device and, and a second capacitor connected in series between the second resistor and the line isolation device, and ii) a first inductor connected in parallel with the first resistor and a second inductor connected in parallel with the second resistor.
