Abstract
A test circuit that is particularly suitable for inclusion on an LSI chip when testing a new technology or process. The circuit will enable accurate determination of the effects of loading on the turn-on and turn-off delays of one or more logic circuits on the chip. These determinations are based upon a comparison of the periods of different signals obtainable from the test circuit.
