Abstract
The present invention relates to a power supply capable of being configured to produce an equivalent negative output resistance or to produce both negative and positive output resistances. The power supply comprises components that can provide equivalent output resistance values that transition from negative values through zero to positive values, and vice versa. By selecting an appropriate negative output resistance for the power supply, the power supply can compensate for the load lead voltage drop caused by the elements (e.g., cabling) between the output sense leads of the power supply and the load. This allows the voltage level provided to the load to be set, or controlled, by setting a voltage level V at the power supply. Preferably, a multiplier chip is used that enables the output resistance values of the power supply to be programmably varied from a negative resistance value through 0 to a positive resistance value, and vice versa. The multiplier chip receives a reference voltage V that can be varied in order to vary the output resistance of the power supply.
