Our mixed-signal ASIC arrived! We are eager to put it into operation 💻🚀
Do you see the resemblance?

We are back!
We finished the first semester with a successful mixed-signal ASIC design. During the meantime, we developed the power electronics necessary to power switched reluctance motors up to 320 Volts! Stay tuned.

During StartUp we measure all phase currents of the SRM after a digitally adjustable time. These have a different di/dt due to different inductance values of the phases at the start position of the SRM.

You can see the current mirror schematic and layout of the HCC .
The resistors and NMOS are built up from multiple identical basic elements in common-centroid arrangement. With this approach the influence of production tolerances is reduced.

Our SPI-based digital interface is tested on an FPGA. 
Via multiple SPI packets, the string "Digitale Schnittstelle" is written into eight registers which are linked to a display as visual feedback.

Part of the @EDRT_RIDE ASIC is the digitally adjustable hysteresis of the motor control. The hysteresis is implemented by using the current bank and the comparator. It can be set using a DAC (A) and a 4-Bit word (B).

An extension of our @EDRT_RIDE to the @EDRT_iSCREAM ASIC is the automatic start of the SRM.
Therefore we have developed the StartUp process, which determines the position sensorless by feeding voltage pulses into the SRM.

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 👀🧠🛠️.
