介绍了一种高效率、低纹波输出的开关电容型DC-DC上变频器。在建议的DC-DC转换器中顺序操作的相同的电荷泵将输出电压纹波的幅度降低到传统转换器的20%。在输出级附近采用PMOS开关的新型电荷泵使DC-DC转换器的功率效率提高了10%。建议的DC-DC转换器，作为一个测试车辆，锁相环电路，这是敏感的电源噪声。所有电路的模拟和制造在0.65-/spl μ/m CMOS工艺。
This paper describes a switched-capacitor type DC-DC up converter with high efficiency and low-ripple output. Identical charge pumps operating sequentially in the proposed DC-DC converter reduce the magnitude of output voltage ripples to 20% of the conventional converters. A new charge pump adopting PMOS switches near the output stage improves the power efficiency of the DC-DC converter by 10%. The proposed DC-DC converter is applied, as a test vehicle, to a phase-locked loop circuit which is sensitive to power supply noise. All circuits are simulated and fabricated in a 0.65-/spl mu/m CMOS process.
