专利范围本专利阐述一个用电压去改变振荡频率的压控振荡器。它仅用少量的线圈和电容构成,易于集成化。对先前所采用的技术描述图1示出先前技术的压控振荡器。图中可以看到,放大器1的输出信号à通过移相器2和3,产生信号(?)和(?),它们分别超前和落后相位θ_1和θ_2,信号(?)和(?)馈送到加法器4,合成信号(?),然后,信号(?)通过谐振电路5正反
Patents This patent describes a voltage-controlled oscillator that uses voltage to change the oscillation frequency. It uses only a small number of coils and capacitors, easy to integrate. Description of Previously Used Techniques FIG. 1 shows a prior art voltage controlled oscillator. As can be seen in the figure, the output signal of amplifier 1 passes through phase shifters 2 and 3 to generate signals (?) And (?) Which respectively lead and fall behind phases θ_1 and θ_2, and signals (?) And Adder 4, a composite signal (?), And then, the signal (?) Passes through the resonance circuit 5 forward and reverse
