How does the Topology of City Streets Impact on their Respective Optimization?
Eric K. Tokuda, Cesar H. Comin, Luciano da F. Costa
Several natural and artificial structures and systems are somehow optimized for performing specific functionalities. The structure and topology of cities is no exception, as it is…
Linearity Analysis of the Common Collector Amplifier, or Emitter Follower
Luciano da F. Costa
A recently introduced Early modeling of transistors is applied to the study of the common collector amplifier (or emitter follower), an important type of electronic circuit typical…
An Early Modeling Approach to Digital Electronics
Luciano da F. Costa
An Early modeling approach of transistors characterized by simplicity and accuracy in representing intrinsic non-linearities is applied to the characterization of propagation delay…
Analysis of the Common Emitter Amplifier Taking into Account Transistor Non-Linearity
Luciano da F. Costa
The operation of a typical common emitter amplifier, including negative feedback, is studied taking into account the non-linearity characteristic of real-world transistors. This ha…
On the Effects of Resistive and Reactive Loads on Signal Amplification
Luciano da F. Costa
The effects of reactive loads into amplification is studied. A simplified common emitter circuit configuration was adopted and respective time-independent and time-dependent voltag…
Towards a Simple, and Yet Accurate, Transistor Equivalent Circuit and Its Application to the Analysis and Design of Discrete and Integrated Electronic Circuits
Luciano da F. Costa
Transistors are the cornerstone of modern electronics. Yet, their relatively complex characteristics, allied with often observed great parameter variation, remain a challenge for d…
Characterizing Complementary Bipolar Junction Transistors by Early Modelling, Image Analysis, and Pattern Recognition
Luciano da F. Costa
This work reports an approach to study complementary pairs of bipolar junction transistors, often used in push-pull circuits typically found at the output stages of operational amp…
A Pattern Recognition Approach to Transistor Array Parameter Variance
Luciano da F. Costa, Filipi N. Silva, Cesar H. Comin
The properties of bipolar junction transistors (BJTs) are known to vary in terms of their parameters. In this work, an experimental approach, including pattern recognition concepts…
An Early Model of Transistors and Circuits
L. da F. Costa, Filipi N. Silva, Cesar H. Comin
Bipolar junction transistors (BJTs) have been at the core of linear electronics from its beginnings. Although their properties can be well represented transport model equations, de…
