Abstract

This paper describes an estimation of the distortion products that arise from power supply noise mixing with the RF signal in a common-source amplifier configuration. Classical Volterra-series system analysis is extended to use on a multiple-input system and the second order supply ripple sidebands are predicted relative to the magnitudes of the input signal and supply ripple. The analysis is shown to be in good agreement with BSIM3v3 simulation and lab measurements in 180nm CMOS: ripple sidebands match within 1-2dBc for a wide range of output power
