Abstract
一种振荡器,用以提供低相位噪声,包括:谐振单元(10)、交叉耦合的电流源单元(30)、和耦合在电流源单元(30)和谐振单元(10)之间的正反馈单元(20);谐振单元(10),用于产生具有第一振荡频率的差分振荡信号;正反馈单元(20)用于接收差分振荡信号,并对差分振荡信号做增益增强得到差分输出振荡信号;电流源单元(30),用于为谐振单元(10)和正反馈单元(20)提供可调偏置电流。由于电流源单元(30)为正反馈单元(20)和谐振单元(10)提供可调偏置电流,并与正反馈单元(20)构成Gm‑boosted结构,使得正反馈单元(20)能够对接收到的差分振荡信号做增益增强得到差分输出振荡信号,因此,可以在保证振荡器正常启动的条件下,通过减小偏置电流,降低振荡器的功耗。
