High speed dynamic MOS capacitor pull-up circuits

MOS capacitor pull-up circuits have been studied for high speed MOS digital circuits (1,2), where they are of interest because the output is derived on the leading edge of the clock pulse, with essentially instantaneous precharge by displacement current. The upper frequency limit has however in the past suffered from charge injection into the substrate (2). This paper will detail a successful solution to this problem, with experimental circuit confirmation and discussion of applications including timing circuits, fast decoding, and general logic.
