摘要： PROBLEM TO BE SOLVED: To provide a digitally controlled oscillation device that implements a reduction in DNL.SOLUTION: The digitally controlled oscillation device exemplarily comprises: an amplification circuit block AMPBK; coil elements LP, LM; and a plurality of unit capacitance units CIU all coupled in parallel between oscillation output nodes OscP, OscM, and each of CIU includes capacitive elements CIp, CIm and a switch SWI for selecting whether or not to permit CIp, CIm to contribute as setting parameters of oscillation frequency. SWI is driven by an on/off control line BIT_CI from a decoder circuit DEC, and BIT_CI is shielded by a shield part GS between OscP and OscM.

摘要： PROBLEM TO BE SOLVED: To provide a digitally controlled oscillation device and a high frequency signal processing device that reduce noise remote from an oscillation frequency.SOLUTION: A plurality of unit capacitance units CIU[1]-CIU[k] are, for example, used to implement a fractional capacitance. In CIU[1], capacitive elements CFXp[1], CFXm[1] have ends on one hand connected to oscillation output nodes OscP, OscM, respectively. Meanwhile in CIU[2]-CIU[k], capacitive elements CFXp([2]-[k]), CFXm([2]-[k]) have ends on one hand connected to a fixed voltage V6. In CIU[1]-CIU[k], the capacitive elements on one side have the other ends connected in common (SWFD), and the capacitive elements on the other side have the other ends also connected in common (SWFS). Switches (SWF1-SWF3) in CIU[1]-CIU[k] are turned on/off by common control.
