TL;DR: This work focuses on a recently illustrated strategy for the testing of analog 2nd order filters, showing that the COBT dynamics is quite similar to that expressed by Resonate & Fire (R+F) neuron models.
Abstract: Recently, proposals have been made for enhancing the Oscillation Based Test (OBT) methodology by using non-plain oscillation regimes, leading to so called Complex Oscillation Based Test (COBT). Here we focus on a recently illustrated strategy for the testing of analog 2nd order filters, showing that the COBT dynamics is quite similar to that expressed by Resonate & Fire (R+F) neuron models. In this interpretation, the testing approach can be related to firing-rate measures. A brief description is given of the mathematical models necessary to achieve a precise characterization of firing times, showing how it can be used for testing purposes. A practical example with simulation data is also provided.

TL;DR: A new Level-Crossing ADC (LCADC) architecture is introduced which employs the novel use of a clocked comparator and can measure a timing noise spectrum with wide dynamic range and wide frequency range.
Abstract: This paper introduces a new Level-Crossing ADC (LCADC) architecture which employs the novel use of a clocked comparator. The proposed LCADC can measure a timing noise spectrum with wide dynamic range and wide frequency range. An extension of the underlying theory of the performance measurement of an LCADC is also included.

TL;DR: In this article, a data processing system that processes input data, comprising a data generating apparatus that generates the input data and data processing apparatus that processes the inputs generated by the data generator, is presented.
Abstract: Provided is a data processing system that processes input data, comprising a data generating apparatus that generates the input data and a data processing apparatus that processes the input data generated by the data generating apparatus. The data processing apparatus includes a time interpolation section that generates time interpolated data, in which level differences between pieces of data adjacent in time are a constant value, based on the input data.

TL;DR: An improved design for a Level-Crossing ADC (LCADC) that incorporates both an equivalent-time method and a clocked comparator is presented.
Abstract: This paper presents an improved design for a Level-Crossing ADC (LCADC) that incorporates both an equivalent-time method and a clocked comparator. The LCADC is experimentally validated using a 65 nm clocked comparator.
