Abstract:
A circuit device suitable for use in performing a DC parametric test on an external load, said circuit device comprising:a. an input suitable for receiving a forcing parameter signal; b. an output suitable for releasing to the external load a signal approximating the forcing parameter signal; c. a first circuit segment between said input and said output comprising: i. a search entity; and ii. an intermediate voltage point; iii. an internal load between said intermediate voltage point and said output; d. a second circuit segment connected in a feedback arrangement with said first circuit segment, said second circuit segment providing the search entity in the first circuit segment with a first voltage signal indicative of the voltage at the output; e. said search entity being adapted for: i. generating a second voltage signal on the basis of said forcing parameter signal and the first voltage signal received from said second segment; ii. applying said second voltage signal to said intermediate voltage point thereby causing a change in either one of the voltage signal or the current signal at said output such that a signal approximating the forcing parameter signal is caused at said output.
