摘要

本文导出了CMOS LC差分振荡器振荡幅值的新表达式。与传统的假设源耦合对流过LC槽的电流为方波的表达式不同，本文的表达式假设源耦合对流过LC槽的电流为截短的正弦波，更符合实际情况。通过与仿真结果的比较，发现新的振荡振幅表达式比常用的传统表达式更精确。

A new expression for oscillating amplitude of CMOS LC differential oscillator

In this paper, a new expression for oscillating amplitude of CMOS LC differential oscillator is derived. Contrary to the conventional expression which was derived by assuming that the current from sourced coupled pair flowing though LC tank is a square wave, the proposed expression is derived by assuming that such current is a clipped sinusoidal, which is more in line with the real situation. By comparing to the simulation results, it was found that the new expression of oscillating amplitude is more accurate than the widely used conventional expression.
