    • The present disclosure relates to a frequency synthesizer. The frequency synthesizer includes a phase comparator having first and second input nodes. The first input node receives a reference signal having a reference frequency. A channel control block has an input that receives a channel word and an output coupled to the second input node of the phase comparator. A local oscillator (LO) output node provides an LO signal having an LO frequency based on the reference frequency and the channel word. A feedback back couples the LO output node to the second input node of the phase comparator through the channel control block. A non-linear error correction element is operably coupled on a coupling path extending between the phase comparator and the DCO.
    • 本公开涉及频率合成器。 频率合成器包括具有第一和第二输入节点的相位比较器。 第一输入节点接收具有参考频率的参考信号。 信道控制块具有接收信道字的输入和耦合到相位比较器的第二输入节点的输出。 本地振荡器(LO)输出节点基于参考频率和通道字提供具有LO频率的LO信号。 反馈反馈通过信道控制块将LO输出节点耦合到相位比较器的第二输入节点。 非线性误差校正元件可操作地耦合在相位比较器和DCO之间延伸的耦合路径上。
