    • A cross-coupled voltage controlled oscillator having reduced phase noise. A pair of bipolar transistors having common emitter connections are coupled to reduce that oscillation frequency which is determined from a tuning circuit connected across the collectors of transistors. First and second varactor diodes provide analog tuning of the circuit, and a digitally controlled capacitor provides for a selection of a band of frequencies to be tuned by the varactor diodes. A current source provides the current to the emitter connections of the bipolar transistors. Second harmonic signals generated at the emitter of the transistors are significantly suppressed by a tuned filtered trap connected to the common emitter connections. By reducing the second harmonic signals, the phase noise or the voltage controlled oscillator can be significantly improved.
    • 具有降低的相位噪声的交叉耦合压控振荡器。 耦合具有公共发射极连接的一对双极型晶体管,以减小由连接在晶体管的集电极上的调谐电路确定的振荡频率。 第一和第二变容二极管提供电路的模拟调谐,并且数字控制电容器用于选择要由变容二极管调谐的频带。 电流源将电流提供给双极晶体管的发射极连接。 通过连接到公共发射器连接的调谐的滤波陷波,显着地抑制在晶体管的发射极处产生的二次谐波信号。 通过减少二次谐波信号,可以显着提高相位噪声或压控振荡器。
