Title: Integrated circuit for high-frequency reception and high- frequency receiving apparatus equipped with the same
Inventor: AKIYAMA TOSHIFUMI
IPC: H03L7/183
Filed: 2002-04-26
Abstract: <P>PROBLEM TO BE SOLVED: To secure an excellent phase noise characteristic even when a tank circuit including an inductor deteriorating the phase noise characteristic is incorporated in an integrated circuit for high-frequency reception.  <P>SOLUTION: A reception IC 1, while controlling the oscillation frequency of a VCO circuit 1f generating a 1st local signal by an integer frequency dividing ratio type PLL circuit 1h at step frequency intervals, controls the oscillation frequency of a VCO circuit 1g generating a 2nd local signal by a fraction type frequency dividing ratio type PLL circuit 1i at step frequency intervals. Phase noise of a PLL circuit is worse as the step frequency of the integer frequency dividing ratio type PLL circuit 1h becomes smaller (the frequency dividing ratio becomes larger) and also worse as the reference frequency of a reference signal generator 5 is lower as to the fraction type frequency dividing ratio type PLL circuit 1i. For the purpose, the step frequency of the VCO circuit 1f is equalized to the reference frequency and made higher than before and the high reference frequency is used for a PLL circuit 1i as it is without being divided.  <P>COPYRIGHT: (C)2004,JPO
