In this paper, a boost converter is proposed, which adopts an adaptable current-limited PFM circuit to decrease the output voltage ripple. Unlike the conventional current-limited circuits, the proposed current-limited circuit could provide the appropriate current to the output load. This is realized by using an adaptable loading feedback circuit to automatically adjust the current-limited current...
This paper presents a new temperature compensation generator (T.C.G.), which is added to a conventional bandgap reference circuit to improve the temperature drift within wider temperature range. The proposed circuit, which operates under the voltages for portable applications, for example 2.5V~5V, has good performances of the line regulation and the temperature coefficient. The proposed circuit is...
In this paper, a new delay-locked loop (DLL) architecture is proposed to effectively improve the DLL jitter performance. A novel realignment duty cycle corrector (RDCC) is proposed for the DLL. The RDCC circuit can make the output waveform of the DLL maintain a 50% duty cycle in a lock mode. The RDCC circuit has advantages of low power consumption, small chip area and high operating frequency. The...
