MATLAB & VHDL-AMS co-simulation environment for IR-UWB transceiver design

Abstract

This paper presents a MATLAB-VHDL-AMS computer aided design automation flow for the design of an IR-UWB transceiver. The co-simulation environment helps the user to create the transceiver system in a top-down design methodology. The constructed CAD flow enables the user to analyze the performance of the system with the aid of BER vs EB /N0 figures. The effect of system and circuit level parameters on the system performance can be analyzed and these parameters can be determined from the model. The transceiver system model is based on circuit parameters such as gain, linearity, and reflection coefficient. The individual system blocks can be interchanged with actual circuit designs. Therefore, the performance of these individual blocks in a transceiver system can also be studied.
