ing operation up to 83. for Si-based ridge-waveguide InAs/GaAs QD lasers with as-cleaved facets. The optical and electrical properties of InAs/GaAs QDs grown on Si substrates were further investigated to evaluate the potential for Si-based photodiodes. A peak responsivity of 5 mA/W was observed at 1debris 发表于 2025-3-23 14:15:58
0893-3405 mulation tools were a research curiosity and in general were mistrusted by most designers and test engineers. In those days the programs were not user friendly, models were inadequate, and the algorithms were not very robust. The demand for simulation tools has been driven by the increasing complexiBACLE 发表于 2025-3-23 19:38:34

Introduction, a circuit schematic. This step relied heavily on the human designer’s intuition, past experience, and knowledge to make reasonable approximations. This was followed by the “breadboarding” phase in which an actual prototype of the circuit was constructed from discrete components interconnected by ex混合,搀杂 发表于 2025-3-24 08:09:17
Overview of Simulation Techniques,e performance of the design before going into the expensive and time-consuming manufacturing process. There are two basic approaches to simulating an integrated electronic circuit. The first, and more traditional, approach is to treat the circuit as a continuous dynamical system and obtain a set ofFIN 发表于 2025-3-24 13:38:41

Switch-Level Timing Simulation,denote the ordering in which the SCCs have been scheduled for processing as described in Section 3.4. If an SCC is simple, i.e., it consists of exactly one block with no internal feedback, then it is simulated at the switch level by algorithms described in this chapter.

Simulating Strongly Connected Components,presented splits the entire time-interval of interest into various time-slots or windows such that all pairs of signal-transitions take place entirely within one of these windows. This is achieved by maintaining a sequential-list of intervals of transitions which is updated dynamically as the algorigoodwill 发表于 2025-3-25 01:45:16
Introduction,is was followed by the “breadboarding” phase in which an actual prototype of the circuit was constructed from discrete components interconnected by external wires and was tested. The performance of the circuit, if not found satisfactory, was then improved by adjusting the circuit element values in a somewhat trial-and-error fashion.
