Abstract

A purely mathematical,behavioral model for Voltage Controlled Oscillators (VCO)is derived.It is based on a Non-Linear Discrete Convolution approach [1 ] whichllows a time-domain formulation compatible with commercial system-level simulators.The approach enables the VCO nonlinear dynamics to be described with great accuracy and computational efficiency,and its influence on the performance of an entire subsystem to be investigated. Model validation,implementation in commercial system- level simulation tools as well as application examples are provided in the paper.
