An analog system's performance can be influenced by many factors such as age-dependent degradation effects which need to be considered during the design process. Transistor level degradation analysis is very time-consuming for large and complex circuits. Behavioral models can be used to speed up the simulation and enable an evaluation on a higher(More)
—In this paper a reliability-aware design method based on the gm /I D-methodology is presented which allows designers of integrated analog circuits to consider process as well as environmental variations and aging effects already at early design stages. Within this method the whole simulation effort is shifted to a single transistor level. With a generated(More)
Ring oscillators exhibit a strong temperature dependency. Additionally, degradation in CMOS transistors affects the performance of circuits over time and is strongly dependent on temperature during circuit operation. In order to design robust and reliable ring oscillator-based circuits, both temperature dependencies have to be considered. This work(More)
In this paper a Reliability-AwaRE (RARE) method based on the gm/ID-methodology is presented which allows designers of integrated analog circuits to consider process as well as environmental variations and aging effects already at early design stages. The proposed method makes aging simulations on system level superfluous by utilizing a stochastic Look-Up(More)
