Complete time-domain behavioral model of Sample-and-Hold Amplifier using SIMULINK®

The paper describes a SIMULINK^reg model for the complete time-domain behavioral simulation of Sample-and-hold Amplifier (SHA). To this purpose, the parameters which affect the operations of a basic SHA blocks are investigated and the non-ideal parameters of these blocks are modeled by using SIMULINK^reg. The black-box description achieved gives the advantage that parameter extraction can be done starting from data sheet parameters without interesting the internal circuital structure of the composing blocks. An example using a sinusoidal test signal is reported in order to test the proposed model.
