SystemC Simulation of Continuous-Time $Sigma-Delta$ Analog-Digital Converters in the Presence of Non-linearities
نویسندگان
چکیده
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 expressed using piecewise linear (PWL) models.

Time-Mode Signal Quantization for Use in Sigma-Delta Modulators
The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...

—For the design of complex systems both accurate and abstract models are required. Especially for analog subsystems this trade-off is difficult. The new SystemC AMS extensions [7] offer high simulation performance, but also serious restrictions. In this paper we model a switched capacitor sigma delta mod-ulator using the SystemC AMS extensions. The model combines high simulation performance whi...
