Fully Integrated High Voltage Charge Pump for Energy-Efficient Reconfigurable Multi-Band RF-Transceivers

Free registration required

Executive Summary

This paper presents a fully integrated high voltage charge pump which enables a reconfigurable, energy-efficient multi-band transceiver. Using a high voltage CMOS technology from Austria microsystems and a 4-phase charge-pump (DC/DC converter) circuit architecture, up to 120 V supply voltage can be generated from a 3.7 V DC battery using this monolithically integrated circuit. The very small footprint of this solution enables the integration of this multi-band transceiver in mobile devices, whereas the concept of reconfigurability can also be applied to fixed transceiver installations to optimize power efficiency.
