High Level Synthesis of Linear Analog Systems

چکیده
This paper presents a unified framework for high level synthesis of linear analog systems, which is now an important research area in analog VLSI systems design. The salient features of this synthesis methodology are automated synthesis of system architectures and performance optimization by architectural exploration method. Operational transconductance amplifier (OTA) and capacitor (C) based implementation style has been adopted for the synthesis step. The entire framework is illustrated with the case study of a low pass filter and the benefits of the approach are clearly brought out.

Exploration-based high-level synthesis of linear analog systems operating at low/medium frequencies
This paper presents a methodology for high-level synthesis of continuous-time linear analog systems. Synthesis results are architectures of op-amps, sized resistors and capacitors such that their ac behavior and total silicon area are optimized. Bounds for op-amp dc gain, unity-gain frequency, input, and output impedances are found as a byproduct of synthesis. Subsequently, a circuit synthesis ...
متن کاملBehavioral modeling for high-level synthesis of analog and mixed-signal systems from VHDL-AMS
High-level synthesis is highly demanded for managing the complexity of analog and mixed-signal system designs. However, synthesis methods are currently in their infancy. The absence of a high-level specification notation is an important limitation for the development of efficient synthesis methods. This paper presents a behavioral model and a VHDL-AMS subset for high-level synthesis of analog a...

The integer word-length optimization known as range analysis (RA) of the fixed-point designs is a challenging problem in high level synthesis and optimization of linear-time-invariant (LTI) systems. The analysis has significant effects on the resource usage, accuracy and efficiency of the final implementation, as well as the optimization time. Conventional methods in recursive LTI systems suffe...
متن کاملTowards a Specification Notation for High-Level Synthesis of Mixed-Signal and Analog Systems
This paper discusses aBlox a specification notation that we defined for automated synthesis of mixed-signal systems. aBlox addresses two important aspects of mixed-signal system specification: (1) description of functionality and performance issues and (2) expression of analog-digital interactions. The semantics of aBlox embeds concepts and rules of a computational model that we developed for m...
متن کاملImplementing the Lorenz oscillator with translinear elements
Nonlinear processing is often more suitable than the traditional linear approach is for analyzing biological signals. Unfortunately, digital nonlinear operations are computationaly expensive. In contrast, a large variety of nonlinear operations can efficiently be implemented in analog electronics, operating at real-time speeds. The low level of accuracy generally associated with analog processi...
