The invention discloses a pattern of arrangement of an electronic element and a voltage-controlled oscillator and particularly relates to a pattern of arrangement of an electronic element. The pattern of arrangement is applicable to the arrangement of N electronic elements, wherein, N is an odd number and the N electronic elements comprise a first group of electronic elements and a second group of electronic elements; the first group of electronic elements is arranged according to a first predetermined mode while the second group of electronic elements is arranged according to a second predetermined mode and the second group of electronic elements is adjacent to the first group of electronic elements. The pattern of arrangement of the electronic element and the voltage-controlled oscillator provided by the invention can ensure that the voltage-controlled oscillator can correctly control the output phase difference so as to achieve the even phase deviation among stages of the whole voltage-controlled oscillator.
Description
technical field [0001] The present invention relates to an arrangement of electronic components, in particular to an arrangement of integrated circuit layout of electronic components. Background technique [0002] A general voltage controlled oscillator (Voltage Controlled Oscillator, VCO) is mainly based on a structure with an odd number of inverters as its main axis of work, and uses the delay time required by each inverter to form its oscillation waveform. If there are N stages of inverters , the period is 2N×tp (propagation-delay), the oscillation frequency is 1 / (2N×tp), the inverter is controlled by the voltage input to the input terminal to perform internal frequency oscillation, and the output terminal Generate an output frequency. [0003] see figure 1 , figure 1 It is a schematic layout diagram of an integrated circuit (Layout) of a multi-stage inverter in a known voltage-controlled oscillator. like figure 1 as shown, figure 1 Taking the known voltage controll...
