course objective
Being capable to specify and design the most essential basic functions (amplifiers and analog level shifts) for interfacing with sensors, actuators, AD and DA converters.
target group
This course is meant for designers of embedded systems.
starting level
Participants should have the knowledge implied by the courses:
target level
At the end of this course participants will be able to specify and realize amplifiers and analog level shifts. This involves using standard integrated circuits (operational amplifiers and references) and passive components. The following aspects have to be taken into account:
- Desired type of amplifier regarding the application
- Noise behavior
- Load drive capability, linearity and overdrive recovery
- Dynamic behavior and frequency stability
- Temperature stability
- Suppression of interference signals
final assignment
The final assignment consists of designing an application-specific amplifier with one or more operational amplifiers.
duration
This courses lasts six days:
- Five days with theory and practice
- One day for participants’ final presentations
description
In electronic systems, signal processing is performed more and more digitally. Analog functionality is often limited to:
- Acquiring and conditioning of analog signals so they can be digitized by AD converters
- Driving actuators
The courses Embedded Analog Electronics 1 and Embedded Analog Electronics 2 focus on specifying, designing and/or applying the most essential analog functions for embedded systems using standard integrated circuits and passive components. Transistor-level design of analog functions is dealt with in the courses Analog IC Design and RF IC Design.
This course ‘Embedded analog electronics 1’ offers both a solid theoretical foundation and a practical approach for designing amplifiers. The participants are offered methods to realize the desired characteristics of an amplifier within a set of constraints. This allows them to design application-specific, cost effective and reliable amplifiers in a short time.
