Aircraft vision system Analog Front End

ECSI came to AnSem for the design of an AFE that met the Xi-Channel® system requirements.  A two die solution was devised with the PA and line interface designed in high voltage 180nm BCD CMOS and the remaining circuitry in 130nm CMOS to take advantage of the higher frequency transistors and lower power of...

MEMS driver ASIC for a novel contact lens sensor

AnSem developed an ASIC for Sensimed to mount directly within the contact lens.  The ASIC digitizes the MEMS sensor reading and transmits the measurements back to the recorder via the same RF link used to power the device using load modulation techniques. By choosing ON Semiconductor's I3T50 0.35 µm...

High Voltage MEMS array

AnSem designed an ASIC containing all the supporting circuitry for the MEMS. On this ASIC, the MEMS array is postprocessed after regular CMOS silicon processing. Each MEMS is programmed by a control voltage with a range between -15V and +15V relative to the silicon substrate. The voltage at each MEMS is controlled by...
