Experimental operation of time-mode building blocks using a time-mode switched-delay unit

This paper provides experimental verification of the functionality of some existing basic time-mode signal processing (TMSP) building blocks having an all-digital advantage. Experimental data that covers all necessary aspects of operation such as transfer functions, linearity and frequency response is presented. Simulations are compared to measured data and performance limitations are introduced such as the hard linearity limit imposed by the switched-delay unit discharge time. In addition, some of these building blocks were used to design a second-order filter for the first time demonstrating a peak SNDR value of 45.5 dB making it a good candidate for data conversion applications.
