Abstract: A programmable delay device that provides delays of more than 100 ns over a broad bandwidth is disclosed. The device includes an input stage that employs M sampling switched capacitor elements such that each sampling switched capacitor element samples at a rate of only 1/M of the fundamental sampling rate. The device includes a programmable delay stage with M programmable switched capacitor banks, each programmable switched capacitor bank having N delay switched capacitor storage elements. Thus, the programmable delay stage includes a total of M×N delay switched capacitor storage elements, thereby reducing the sampling rate by a factor of M×N. This reduced sampling rate permits much smaller sampling switches, resulting in reduced leakage current and enabling far longer programmable delay times. Lastly, the device includes an output reconstruction stage that reconstructs a delayed version of the input RF signal by combining signals from the programmable delay stage.

Abstract: In a predictor device, a method for predicting a metric of a contact center includes receiving contact center operational data associated with a time duration; training a set of algorithms and their available hyperparameters with the contact center operational data to generate a set of data models; generating a score associated with each data model of the set of data models, the score quantifying a performance of each algorithm and its available hyperparameters on the contact center operational data; identifying the data model having the largest score as a best learning model for the time duration; and generating a contact center metric prediction based on the best learning model for the time duration.
