摘要: An oscillator is formed by a resonator (RES) coupled to an amplifier (AMP) via a coupling path (COP). In order to counter unwanted oscillations due to parasitic resonances in the coupling path (COP), the coupling path (COP) includes a series resistance (RS). To improve the noise-performance even more a series capacitance can be included in the coupling path (COP). Such a series capacitance will also effectively widen a frequency range over which the oscillator can be tuned.

摘要翻译: 振荡器由通过耦合路径(COP)耦合到放大器(AMP)的谐振器(RES)形成。 为了抵消由耦合路径(COP)中的寄生谐振引起的不想要的振荡,耦合路径(COP)包括串联电阻(RS)。 为了提高噪声性能,甚至可以在耦合路径(COP)中包含一个串联电容。 这样的串联电容也将有效地扩大振荡器可以调谐的频率范围。
