It is an innovative idea for modern PLL generation to control the bandwidth proportionally to a reference frequency. Recently, a frequency of the operating clock in microprocessors has been required to be changed frequently and widely in order to manage power consumption and throughput. A new switched capacitor(SC) filter which has fully flat response has been developed. We have also developed a new digital control method for realizing adaptive biased PLL with the widest frequency range. The measured performances of the test chip were good enough for the use in the microprocessors. |
