Abstract

一种锁频环、电子设备和频率生成方法。该锁频环(10)包括：控制电路(11)，被配置为判断输入频率(fi)和反馈频率(fb)的大小关系以得到控制信号，并根据控制信号确定频率控制字(F)，其中，控制信号包括第一子控制信号(Cf)和第二子控制信号(Cs)，当输入频率(fi)大于反馈频率(fb)时，控制电路(11)被配置为生成第一子控制信号(Cf)，当输入频率(fi)小于反馈频率(fb)时，控制电路(11)被配置为生成不同于第一子控制信号(Cf)的第二子控制信号(Cs)；数字控制振荡电路(12)，被配置为根据频率控制字(F)，生成并输出具有目标频率(fdco)的输出信号(Sout)。
