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...

Ultra low-power FM receiver for hearing aid

AnSem developed for Phonak an ultra low-power miniature FM receiver chip supporting multi-frequency technology to allow the device to pick up FM transmissions directly from the classroom teacher thus improving the signal to noise ratio perceived by the hearing aid user by up to 20dB. This means that, for the first...

Energy scavenging ULP transceiver

To meet this market demand, AnSem developed an ultra low-power RF ISM FSK transceiver in 0.25µm CMOS with a operational voltage range 0.9 V to 1.6 V and a power consumption of 2.6mW for transmission / 1.2mW for reception. The device is highly flexible including: Programmable frequency channels with 60 Hz...

Ultra low-power RF CMOS ISM transmitter

To service these applications AnSem developed an ultra low-power RF ISM transmitter in 0.25µm CMOS with an active power consumption of 2.6mW - 10 times lower than any other product available today. The transmitter's low operating voltage - as low as 0.9V - and wide supply voltage range makes...
