<P>PROBLEM TO BE SOLVED: To provide a control circuitry which corrects a temperature drift possibly occurring to a synthesizer during a continuous operation. <P>SOLUTION: The control circuitry comprises: first control means operable to generate a first control signal, the first control signal being indicative of a relationship between an output signal and a first reference signal, and to generate the output signal in dependence upon the first control signal, the first control means being configured to tend to maintain a first desired relationship between the output signal and the first reference signal in response to the first control signal; and second control means configured to influence operation of the first control means in response to the first control signal by way of a second control signal so as to tend to maintain a second desired relationship between first control signal and a second reference signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
