PLL circuit and electronic equipment

The invention provides a PLL circuit and electronic equipment. The PLL circuit comprises a charge pump and a current input module; the charge pump is used for receiving a control signal, and the control signal is used for controlling the charging current and the discharging current of the charge pump; one end of the current input module is connected with a voltage input end, and the other end of the current input module is connected with the output end of the charge pump; the current input module is used for outputting target current. Namely, the PLL circuit is externally connected with a current input module at the output end of the charge pump, so that the on/off time sequence of the charge pump of the PLL circuit is changed, the decimal modulation mode is further changed, and the purpose of optimizing the decimal stray is achieved. 本发明提供了一种PLL电路及电子设备，PLL电路包括：电荷泵以及电流输入模块；所述电荷泵用于接收控制信号，所述控制信号用于控制所述电荷泵的充电电流以及放电电流；所述电流输入模块的一端与电压输入端连接，另一端与所述电荷泵的输出端连接；所述电流输入模块用于输出目标电流。也就是说，该PLL电路通过在电荷泵的输出端外接一个电流输入模块，以此改变PLL电路电荷泵
