Patent ID: 8093875

Claim:
A voltage programming circuit, comprising: a base unit adapted to provide an output voltage; a cable adapted to couple the output voltage from the base unit to a remote load and create a load voltage; a reference line, disposed within the cable, adapted to couple the load voltage at the load back to the base unit; a cable cancellation network adapted to compensate for total voltage drop between the base unit and the load due to the cable; and a tip adapted to operably and securely couple the cable to the load; wherein the load voltage is: Vout ′ = ( R ⁢ ⁢ 1 + R ⁢ ⁢ 2 ) R ⁢ ⁢ 2 · ( Vref ) · n , wherein Vout′ is the value of the load voltage; Vref is the value of a reference voltage; R 1 is the value of a first resistor; R 2 is the value of a second resistor; and n is the value of a voltage adjustment.
