Hello Twitter We are students from @HS_Reutlingen and @ElectronicsDrv designing an ASIC on the base of our predecessors @EDRT_iSCREAM. We are excited to share our project! Expect interesting content in the upcoming time 👀🧠🛠️. #PowerElectronics #Microelectronics

What a journey it was! Thanks a lot to everyone interested in our project. While we say goodbye, another team will work on cool improvements of the ASIC such as automatic start position detection and a digital interface. So head over to @EDRT_RIDE to stay tuned!

It's a match! On the left you can see the final simulations just before chip tape-out and on the right the latest ASIC measurements from the lab on real hardware. #electronics #simulations #ASIC

For the simulaton we utilized VHDL-AMS to descibe a variable inductance modeling the changing inductance of a switched reluctance motor while spinning.

And for the lab measurements, well, a real switched reluctance motor!
From idea to concept to design to reality! Here you can see the different project stages which we passed in the last months. #electronics #engineering #ASIC

The iDream comes true! The ASIC is able to control a switched reluctance motor with a DC link voltage of 300V and 5400 rpm. #ASIC #electronics #Engineering

Here you can see a little deeper inside the mechanics of our SRM! One can easily identify the distict coils and the rotor. No permanent magnets necessary! #electronics #Engineering

We made it. Within 4 months we designed a CMOS ASIC based on the @XFAB_FOUNDRY's analog IP library for our #Master project. The layout data has already been sent in and we look forward to holding the chip in our hands and testing it. Stay tuned! #Microelectronics @ElectronicsDrv

Diving into our ASIC's details manufactured by @XFAB_FOUNDRY in a 350 nm process. In the pictures below you can identify the analog and digital parts of our circuit as well as our crystal clear logo! #electronics #engineering #semiconductor

Putting the "I" into "IC": Our SR-Motor-Control-ASIC integrates the analog current control loop, the digital state machine for phase activation and the digital logic to detect the rotor position via the PWM frequency. #electronics #microelectronics #engineering

So if you are planning to use a 8/6 switched reluctance motor in your application you just need some current sensors, a power stage and our ASIC! No need to worry about position detection or current control anymore.

Here you can see the state machine inside our ASIC switching through its internal states!

The ASIC is in place and running! What a relief after two terms of hard work and dedication. More details to come #microelectronics #engineering

The first glimpse of our chip in reality! Due to a little bonding mistake this specific one becomes a viewing example but fortunately we got 49 others. #ASIC #microelectronics #semiconductor
