| 摘要 |
A frequency synthesizer capable of high speed, low power, wideband operation including a method of gain compensation, and a method of fast voltage controlled oscillator (VCO) band calibration. In addition, the frequency synthesizer may include two or more switchable independent loop filters to facilitate wideband operation. Such a frequency synthesizer may be used in many applications, and in one example, may be particularly suitable for use in a multi-band, multi-standard transmitter or radio transceiver.
