Abstract

See full text

A device comprising a device under test and a time to current converter configured to be coupled to the device under test. The device under test comprises: (i) at least one delay element for creating a delay; (ii) at least one capacitor for providing capacitance loading to the at least one delay element; and (iii) at least one switch to control the capacitance loading provided by the at least one capacitor. The time to current converter comprises (i) a first input for receiving a first clock signal; (ii) a second input for receiving an inverted and delayed version of the first clock signal from the device under test; and (iii) an impedance module for measuring an output current. During a testing mode, the at least one switch is in a closed position so the at least one capacitor can provide a capacitance loading to the at least one delay element to amplify the delay associated with the device under test.
