Application and evaluation of the RF charge-pumping technique [PDF]

, 2008
In this paper, we will discuss the extendibility of the charge-pumping (CP) technique toward frequencies up to 4 GHz. Such high frequencies are attractive when a significant gate leakage current flows, obscuring the CP current at lower pumping ...
