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 …

Analysis of soft charging switched capacitor power converters
Switch capacitor converters are a microcosm in the world of power converters and as such have received little attention in both research and application. There is a perception that they possess many undesirable operating characteristics, such as inefficiency, poor output regulation and tracking, …

A Two-Stage Piezoelectric Resonator and Switched Capacitor DC-DC Converter
… based on piezoelectric resonators (PRs) and capacitors as the main passive elements. In previous work, we have demonstrated that PRs have high efficiencies and power density capabilities operating as dc-dc voltage regulators, but that these advantages wane for high step down ratios. …

Alternative topologies for the low-voltage buck converter
… was performed. The three level buck, Resonant Switch Capacitor (ResSC), and Cuk-Buck2 were selected to be studied further based on the fact that they contain few components and were discovered in this work to have the possibility of operating at fixed frequency while smoothly regulating output …

High frequency AC power converter for low voltage circuits
… a 3-phase rectifier bridge. In addition, a novel switch-capacitor rectifier capable of 3V, 1W output, was evaluated as an alternative circuit to the diode rectifiers. A 50MHz prototype of each version of the system was designed and built for a 12:1 conversion ratio with 24Vpp line-to-line AC …

The Analysis and Design of Phase-tunable Low-Power Low-Phase-Noise I/Q Signal Sources for Analog Phase Calibrated Transceivers
… using an MOS varactor and a digitally controlled switch capacitor array for frequency tuning, we propose an alternative frequency tuning technique based on the fundamental operation of LC QVCOs. The off-resonance operation, which is defined by the coupling network, suggests varying the coupling …

A Reconfigurable Digital-to-Analog Converter with Supply Invariant Linearity
… and an analog "summing" core utilizing charging capacitors with an operational transconductance amplifier in a voltage-follower configuration. This topology is highly configurable to allow for optimization across process voltages, step sizes and low power operation. The specification of the DAC …
