no. 2 Embodiment approach
[0111] 2.1. Outline of oscillation circuit
[0112] Figure 11 It is a diagram showing a configuration example of the oscillation circuit 12 of the second embodiment. Unlike the first embodiment, the oscillation circuit 12 of the present embodiment includes the generation of the reference voltage V r0 , V r1 , control voltage V C The voltage generation part 60. Also, for Figure 1 to Figure 10 The same elements are denoted by the same reference numerals and explanations thereof are omitted.
[0113] In the oscillation circuit 12 of the present embodiment, the voltage generation unit 60 can easily adjust the reference voltage V r0 , V r1 . Therefore, it is possible to perform fine adjustment so that the variable sensitivity of the varactor diodes 21A, 21B is stable (a state where the frequency change of the oscillation signal is not biased with respect to the control voltage), that is, exhibits better linearity.
