ABSTRACT:
A charge pump for generating an arbitrary voltage level includes “M” pieces of pump units PUiand “M+1” pieces of first switches Sj. The pump unit PUiincludes a first terminal Ni,1coupled to a reference voltage Vi,1, a second terminal Ni,2coupled to a reference voltage Vi,2, a third terminal Ni,3, a fourth terminal Ni,4and at least one capacitor Ci. Ciis charged by Vi,1and Vi,2during a first period, and a voltage is provided from Ni,4by Ciaccording to a voltage at Ni,3during a second period. The first switch Sjis adapted for electrically connecting the first terminal and the second terminal during the second period. The first and second terminals of Skis coupled to Nk−1,4and Nk,3, respectively. The first terminal of S1receives the input voltage and the second terminal of SM+1outputs the output voltage.
