Abstract
The invention relates to a signal generating device (10) for a charge pump for an integrated circuit, comprising:N signal outputs D1, . . . , DN and a signal setting input (12) for setting a frequency f, in which case the signal generating device (10) is designed in such a way thata periodic signal Sx(t) can be output via the signal output Dx,all the signals S1(t), . . . , SN(t) have the same settable frequency f, in which casethe following holds true for the signal Sx(t), where 2≦x≦N,Sx(t)=S1(t−(x−1)·&Dgr;Tx−kx/(2f)),in which case&Dgr;Tx is the delay duration of the signal Sx(t) with respect to Sx−1(t), andkx&egr;{0; 1},the delay duration &Dgr;tx is dependent on the frequency f.Furthermore, the invention relates to an integrated circuit.
