Abstract:	摘要： This study presents a low-power all-digital clock generator (ADCG) for a wide supply voltage range system. The proposed ADCG limits the maximum supply current to 100 μA at a supply voltage ranging from 1.6 to 3.6 V. The ADCG also uses a digitally controlled oscillator (DCO) to extend its operational frequency range. The proposed DCO controls the supply current and divider circuits for a wide supply voltage range. The output duty cycle of ADCG falls within 50 ± 1.9 % using a duty cycle corrector. The maximum peak-to-peak jitter is less than 2.7 % at 8.38 MHz for a digital water meter application (DWM). The operational frequencies of 1.45 and 8.38 MHz at 1.8 V are 3.1 and 36.7 μA, respectively. The core area of ADCG is 0.14 mm 2 for a 0.35 μm CMOS process. The operational frequency of ADCG ranges from 4.5 to 9.2 MHz at a supply voltage ranging from 1.6 to 3.6 V. This clock generator can also be applied to microcontroller applications. 其他題名： Analog Integr Circ Sig Process 出版者： Boston: Springer US 出版日期： 2013-03 出處： Analog integrated circuits and signal processing, 2013-03, Vol.74 (3), p.517-526 版權： Springer Science+Business Media New York 2013 識別號： ISSN: 0925-1030 識別號： EISSN: 1573-1979 識別號： DOI: 10.1007/s10470-012-0022-6
