An oscillator includes an LC tank circuit 140, active devices 131 & 132 and capacitors (passive devices) Ct and Cd. The tank circuit 140 is indirectly coupled to the active devices 131, 132 via the capacitors. The amplitude of the oscillation in the tank circuit 140 is reduced by a ...
由上分析可知,若要在不恶化相位噪声的基础上降低功耗则须:(1)在满足相位噪声和振幅指标要求的前提下适当降低工作电压和电流;(2)选择合适的Ibias值使LC电路工作在电流限制区和电压限制区的临界处;(3)尽可能提高谐振腔中电容,尤其是电感的Q值以降低Rtank的值;(4)适当提高谐振腔中L的值并降低C的值。 2 仿真结果...
