CHARGE PUMP WITH Vt CANCELLATION THROUGH PARALLEL STRUCTURE

摘要

A charge pump circuit for generating an output voltage is described. The charge pump includes an output generation section and a threshold voltage cancellation section, where these sections have the same structure including a first branch, which receives a first clock signal and provides a first output, and a second branch, which receives a second clock signal and provides a second output. The charge pump circuit also includes first and second transistors, where the first and second outputs of the output generation stage are respectively connected through the first and second transistors to provide the output voltage of the charge pump, and where the first and second outputs of the threshold voltage cancellation stage are respectively connected to the control gate the first and second transistors.
