Abstract

Analysis and design techniques of charge-pump-based RF antenna-switch controllers are presented. Loading effects of RF antenna switches that cause voltage drop of the controller have been identified and embedded in the analysis. The proposed analysis also captures effects of MOS-switch on-resistance and parasitic capacitances, so more precise descriptions of the charge-pump output voltage can be obtained. Furthermore, the body biasing technique has been employed to prevent latch-up. The analysis and the design techniques have been verified using a 0.35-mum CMOS technology. RF antenna-switch performances with the designed controller have also been measured and presented.
