This paper presents an analysis of the bias constraints for switching and linear voltage regulators operated in a parallel-hybrid configuration. Particular emphasis is given to polar and envelope-tracking RF power amplifier (PA) applications requiring wideband dynamic voltage regulation. Ideal expressions are derived for the optimum current contribution of the switching regulator under quasi-static operating conditions. In contrast to previous work, it is shown that the optimum mean current… CONTINUE READING
