摘要
利用锁相环重定时技术,采用0.35 /spl μ m CMOS,制作了156mbit /s的3R单片集成电路。我们开发了一种新的电压控制振荡器(VCO),它具有较小的自由运行频率偏差,因此不需要任何调整。我们还开发了一种宽动态范围前置放大器。使用该前置放大器和压控振荡器实现38db动态范围,无需调整锁相环。
A 3R one chip IC at 156 Mbit/s using PLL retiming technology has been fabricated with a 0.35 /spl mu/m CMOS. We developed a new voltage controlled oscillator (VCO) that has less deviation of free run frequency so that any adjustment is not required. We have also developed a wide dynamic range preamplifier. The use of this preamplifier and VCO realizes a 38 dB dynamic range without any requirement for adjustment of a PLL.
