Abstract
An apparatus is provided for on-chip reconstruction of transient settling behavior. The apparatus comprises a first sampling circuit configured to sample a tracked analog signal output from a circuit under test over an operating period at a first sampling time, thereby generating a first sample output. In addition, the apparatus comprises a second sampling circuit configured to sample the tracked analog signal output at a second sampling time, thereby generating a second sample output. The apparatus further comprises a signal subtraction circuit configured to perform subtraction of the first sample output and the second sample output, thereby generating a difference signal. Moreover, the apparatus comprises a signal conversion circuit configured to output the difference signal in the digital domain.
