SJT Micropower Products and IP Areas


Low Dropout Regulators

  • Capacitor Free Operation - Source follower architecture is unconditionally stable
  • High efficiency - extremely low dropout (30mV @ 150mA)

Switching Converters

  • Use existing, older technology high voltage parts with modern low voltage digital CMOS
  • Conversion of voltages on chip

uMICSTM Transceivers

  • Longer Battery Lifetime (2mW @ 100kbps)
  • Extremely low power CMOS transceiver developed for Medical Implants (MedRadio 402MHz)
  • Can be converted to other frequency ranges

RF Power Amplifiers

  • Solves problem of integrating power amplifiers into scaled CMOS
  • High voltage swing allows high power on low voltage digital technologies

Extremely Low Dropout Regulator - LDO

SJT has developed a low dropout regulator with less than 30mV dropout for a 150mA load current that does not need a capacitor at the load to be stable. In addition, there is no charge pump or other circuit which might add noise or complications to the LDO. The regulator is radiation tolerant and has been tested up to 1 MRad. We are developing the regulator for NASA. Please contact us if you would like more information immediately.

uMICSTM Transceiver for MedRadio

As part of an NIH SBIR award, we have developed an extremely low power FSK transceiver. More soon coming soon or please contact us if you would like more information.

RF Power Technologies

We are working on efficient wireless power amplifier modules along with other RF technologies up to 10GHz. The modules are being developed on scaled CMOS 180nm and below. More is coming soon and please contact us if you have any questions.
