摘要：
An apparatus comprising a first circuit, a second circuit and a third circuit. The first circuit may be configured to generate a video input signal having a voltage. The second circuit may have a finite input resistance configured to generate a current in response to presenting the voltage across the finite input resistance. The third circuit may be configured to cancel the current by (i) generating the current in response to presenting the voltage across a replica resistor having a resistance similar to the finite input resistance and (ii) passing the current away from the apparatus.
