This paper presents a method for SystemC simulation of analog systems with nonlinear parameters. Specifically, the paper focuses on Σ−∆ analog-to-digital converters (ADC). The method generates compiled-code simulators based on symbolic analysis. Code is optimized using loop invariant elimination, and constant folding. Circuits are described as structural macromodels. Non-linear parameters are e...

Offset mismatch, gain mismatch, and time-skew error between time-interleaved channels limit the performance of time-interleaved analog-to-digital converters (TIADC). This paper focused on the time-skew error. A new technique for calibrating time-skew error in M-channels TIADC is described, and simulation results are also presented. Keywords—Calibration, time-skew error, time-interleaved analog-...

A digital-to-analog converter system compliant with the requirements of software radio transmission interfaces is presented. The system, through a proper combination of interpolation, digital filtering and data conversion allows us to relax the speed requirements of the analog and the digital section while fully satisfying the specifications. A design example and high level simulation results a...

Analog synthesis tools have traditionally traded quality for speed, substituting simplified circuit evaluation methods for full simulation to accelerate the numerical search for solution candidates. I will argue that this is no longer an acceptable tradeoff: for a synthesis strategy to have practical impact, it must use a simulator-based evaluation engine identical to that used to validate ordi...

Sigma-Delta Analog to Digital Converter with digital implementation techniques is simulated. The differential pin based and inverter based architectures are discussed. Simulation of the proposed architecture with Virtex-4 FPGA I/Os is performed and analysis carried out using HSPICE to estimate the typical achievable clock speeds. The results demonstrate 200MHz clock speeds on LVPECL differentia...

This paper provides an Analog Behavioral Model (ABM) in PSpice of a tunnel diode The PSpice parameters are implemented as separate parameterized blocks constructed from SPICE (ABM) controlled sources and extracted through experiment. A tunnel diode based oscillator is also proposed and simulated using circuit analysis software. The behavior of the tunnel diode is simulated and compared to the m...

Malingering research typically uses analog simulation design or differential prevalence design among "real" patients. Both have been criticized for methodological limitations in external and internal validity, respectively. Samples of simulated malingerers were compared to suspected malingerers to examine generalizability of analog findings. Overall results support the use of simulation designs...

The accurate analog simulation of critical circuit parts is a key task in the R&D process of integrated circuits. With the increasing complexity of integrated circuits it is becoming cumulatively challenging to simulate in the analog domain and within reasonable simulation time. Previous speedup approaches of the SPICE (Simulation Program with Integrated Circuit Emphasis) analog circuit simulat...

Mixed-Mode simulation has been generating considerable interest in the simulation community and has continued to grow as an active research area. Traditional mixed-mode simulation involves the merging of digital and analog simulators in various ways. However, efficient methods for the synchronization between the two time domains remains elusive. This is due to the fact that the analog simulator...
