symulacja obwodu - Opis:
- In this paper an object of analysis and simulation modeling are the basic programmable circuits using CMOS digital potentiometers or Resistive Digital-to-Analog Converters (RDACs). Based on the analysis and principle of operation an improved SPICE-based behavioral model for RDAC potentiometers is created. The model accurately reflects resolution (wiper steps), nominal end-to-end resistance, wiper resistance, linear and nonlinear increment/decrement of the wiper, common-mode leakage current, operating bandwidth, analog crosstalk, temperature coefficients and noise effects. Model parameters are extracted for the dual RDAC potentiometer AD5235 from Analog Devices as an example. The workability of the proposed simulation model is verified by simulation modeling and experimental testing of sample electronic circuits.
