Abstract

PURPOSE:To secure the uniform action characteristics for VCO by providing a DC amplifier at PLL to vary the gain in accordance with the change of the programmable divider. CONSTITUTION:DC amplifier 18 is inserted between VCO13 and phase comparator 15 of PLL frequency synthesizer 5, and the gain of amplifier 18 is varied according to the change of the division ratio of programmable divider 14 in order to decrease the change of the total loop gain for synthesizer 5. As a result, the action characteristics of VCO13 can be stabilized even though the division ratio of divider 14 may be changed greatly.
