Switch capacitor filter design aids
Two aids for the design of switched-capacitor filters (SCFs) are examined: breadboard modelling and computer simulations. A breadbroad was constructed based upon the same passive prototype of a seventh-order integrated filter. The breadboard met the original design specifications better than the …

Circuit level synthesis for delta-sigma converters
… work on a delta-sigma toolbox for MATLAB, the switched capacitor circuit contains robustly generated differential operational amplifiers and comparators. Furthermore, switched capacitors are scaled for minimal kT/C noise while switch sizes are synchronously adjusted to accommodate these values. …

Monolithic low phase noise oscillators for moderate frequency applications
… tuning range of 259MHz-314MHz (extendable with switched capacitors) with a normalized jitter of 102ppm.

A 1.6-3.2GHz, high phase accuracy quadrature phase locked loop
… principle focus herein. The VCO uses digitally switched capacitors to extend the tuning range. It consists of two cross-coupled cores that produce quadrature outputs, where phase error arises if the cores are not identical. The VCO's output also has a controlled amplitude and common mode point. …

Use of Battery Systems for VAR Support in Con Edison’s Distribution Network/Substation
<p>Battery Energy Storage System (BESS) can facilitate the integration of Distributed Energy Resources (DER) and help create a more reliable grid by providing multiple services including reactive power (VAR) support. This research will investigate the use of smart inverters to provide VAR support, …

Energy-efficient Interfaces for Vibration Energy Harvesting
… one is a novel SSH architecture which employs capacitors instead of inductors to perform synchronous voltage flip. This new architecture is named as SSHC (synchronized switch harvesting on capacitors) to distinguish from SSHI rectifiers and indicate its inductorless architecture.
