Abstract
An apparatus for measuring Output Voltage characteristics on a dynamic logic signal at an output of a device under test (DUT) includes a comparator for comparing the voltage at the output with a threshold voltage to generate a control signal. The control signal is used to switch an appropriate current load to the output in response to the dynamic logic signal. A measurement of the voltage at the output provides the Output Voltage characteristics without requiring control of an input stimulus or a static logic level at the output.
Claims1
An apparatus for measuring Output Voltage characteristics on a dynamic logic signal at an output of a device under test comprising:
- means coupled to the output for comparing an output voltage with a threshold voltage to generate a control signal, the threshold voltage being between a “high” state voltage level and a “low” state voltage level;
- and
- means in response to the control signal for applying an appropriate load to the output so the “high” and “low” state voltage levels may be measured to determine the Output Voltage characteristics.
