Student project: Ultra high impedance voltage amplifier 

Develop and build an multi channel amplifier with an input impedance in the terra ohm region for ISE (ion selective electrode) elector chemical measurements 

What you will do

• Gather requirements from stakeholders like lab users for the amplifier use cases 
• Design (schematics and layout), build (or order) and test an amplifier circuit 
• Verify and document the design 
• Expand the design with a multiplexer, precision ADC and optionally a microcontroller and galvanic isolation 
• Optionally design an enclosure (3D printers are available) 

Most important feature is a high input impedance to accurately measure the open voltage of a sensor with a high internal impedance. Furthermore it should contain 4 or 5 amplifier channels and a multiplexer to combine the outputs of these channels either to a connector for an external voltmeter or an ADC integrated in the design itself. 

 

What we do for you

In this internship you will have the opportunity to contribute to innovative research and be an important member of our multidisciplinary development team. We have an electronics lab, chemical lab and a mechanical workshop to support you. And you can learn a lot from the colleagues, and we can learn from you.  

Who you are

• A Bachelor student (HBO or WO) in electronics engineering or a related field
• Electronics knowledge, both analogue and digital (interfaces, actuate and sensing) 
• Very hands-on, soldering experience is a pre 
• Programming experience is a pre 
• Pro-active, outreaching mindset and eager to learn  
• Enjoying working in a team 
• Available for 6 months
