Abstract: PURPOSE:To improve frequency stability without degradation of the characteristic by using an amplitude comparator and a carrier wave gain controller where the control input is connected to the difference components output of the comparator above through a base band amplifier. CONSTITUTION:The AM wave input applied to terminal 1 is detected by diode 14 connected to terminal 11 of amplitude comparator 9, and this detection output is compared with the AM wave comparison input applied to terminal 12 by differential amplifier 16, and the difference voltage between them is output to terminal 13.

Consequently, if a part of the output of controller 10 connected to comparator 9 is taken out from terminal 2, a good AM signal which is the almost same signal as the AM signal applied to terminal 1 and is not degraded and has the same frequency stability as oscillator 6 can be obtained.

IPC: H03L7/093
Filed: 1995-03-10
Abstract: PURPOSE: To quickly switch a frequency and improve C/N and S/N when a target frequency is reached. CONSTITUTION: A VCO 101, a loop filter 102, a PLL 103, and a programmable divider 106 are connected in a loop. The PLL 103 includes a charge pump 103a and a phase comparator 103b. The charge pump 103a has its characteristics switched with the voltage signal from a variable power source 112. When the frequency is switched, characteristics to reach the target frequency can be varied by varying the characteristics of the charge pump 103a. The characteristics are varied so that the switching time becomes short during the frequency switching and necessary S/N and C/N are obtained during and after convergence. The variation is made as smooth as possible so that the frequency nearly reading the target is not disordered.  Consequently, while the quick frequency switching is actualized by varying the characteristics of the system of the PLL during the frequency switching and convergence, the S/N and C/N are improved.
