High-Q Tunable Filters and High Efficiency Charge Pumps

Completed Technology Project

Project Description

High-Q Tunable Filters and High Efficiency Charge Pumps
The supply voltages of modern baseband digital integrated circuits are well below the required actuation voltages for the MEMS tunable filters. Therefore, a charge pump is used to achieve the required high actuation voltage for the MEMS devices. Current state-of-the-art charge pump designs produce output voltage ripples as high as 1 V, which has adverse effects on filter performance, and this is a critical technology gap. The proposed technology will close this gap by delivering two Integrated Circuits (ICs), a high-efficiency charge pump with low-ripple output and a filter design that is immune to bias noise (caused by the ripple).
