A SiGe BiCMOS high voltage driver for Class-S power amplifier

A high voltage driver for Class-S power amplifier using SiGe BiCMOS process is presented in this paper. This high voltage driver is applied for making high voltage swing at the input of a power amplifier. The input of this driver is 600 mVp-p then the measured output is 780 mVp-p for single-ended. This driver dissipates 202 mW and it is suited for processing a bit stream of 2.4 Gbps and can be used as a driver stage for switching power amplifier. This high voltage driver is measured with fabricated delta-sigma modulator module.
