This paper presents a discussion about the performance achievable by an exponential-gain charge pump (i.e., by a charge pump featuring a voltage gain which increases exponentially with the number of stages). This charge pump topology is analyzed in terms of both voltage gain and equivalent output resistance. An analytical expression of these two parameters(More)
This paper presents a study of the theoretical performance of CMOS integrated charge pumps (CPs). The discussion is based on a behavioural model of the CP and a mathematical manipulation of power efficiency definition. The CP theoretical limit is found in terms of both power efficiency and maximum driving capability. The basic idea is to analyze the(More)
