| 摘 要： | 描述了高数据率超宽带调频(FM-UWB)发射机的系统结构和电路设计.该发射机采用内含8相环形振荡器的有限模小数分频型锁相环(PLL)生成频率键控正弦波信号,以降低子载波频率和噪声.该环形振荡器输出的差分正弦波信号直接调制高增益射频(RF)环形振荡器,生成带宽为2 GHz且满足UWB频谱掩膜的信号.在65 nm TSMC...

| Abstract: | Architecture and circuit design of a high data rate frequency-modulated ultra-wideband(FM-UWB) transmitter was described.In this circuit,a finite-modulo fractional-N PLL with an eight-phase ring VCO was used to generate a 2-FSK modulated sine wave with reduced subcarrier frequency and noise.The differential sine wave outputs of the ring VCO directly modulated a high-gain RF ring VCO for nearly 2 GHz UWB mask-compliance signal generation.Finally,a 500 kb/s,low-power,7 GHz to 9 GHz FM-UWB transmitter was impl... |
