Abstract

Disclosed examples include self-biased DLL circuits to generate a bias current signal proportional to a repetition frequency of a first signal representing continuous switching or discontinued switching operation of the DC-DC converter. The DLL circuit includes a monostable multivibrator to provide a pulse output signal in response to an edge of the first signal with a pulse duration set by a control current signal, a phase detector to provide output signals according to a phase difference between an edge of the pulse output signal and the first signal, and an output circuit to provide an output signal according to the phase detector output signals and according to an offset signal, to provide the bias current signal according to the output signal, and to provide the control current signal according to the output signal.
