A Low Spur Charge Pump in 0.35μm SiGe Process for PLL
The operation,design and measurement of a charge pump in a 0.μm Si e process are presented. Measurements show,within the operating frequency range of .Hz to.Hz,that the charge pump achieves a less than 0.mismatch between the source and sin current over the output voltage range of 0.To 2. At power voltage., and the reference spur is below-dBc. The charge pump is used in an integer-PLL for WCDMA applications.
