Rise time and fall time measurement
Among other things, one or more systems and techniques for transition time evaluation of a circuit are provided herein. In some embodiments, a comparator is configured to receive a circuit signal from the circuit. The circuit signal is evaluated by the comparator based upon one or more control voltages to create one or more voltage waveforms. In some embodiments, the one or more voltage waveforms have substantially similar slopes. A time converter, such as a time-to-current converter or a time-to-digital converter, is used to evaluate the one or more output waveforms to determine a transition time, such as a rise time or a fall time, of the circuit. In some embodiments, the one or more output waveforms are used to reconstruct a transition waveform representing a waveform of the circuit signal.
