| Research Abstract |
Fully-differential amplifiers operable from 1V or 0.5V power supply have been designed and fabricated. They show 80dB and 35dB of gain, 10HMz and 30MHz of bandwidth by 200μW and 300μW of power dissipation, respectively. A class of three-phase active complex filter architecture that does not require common-mode rejection has been found by the author and a test chip has been made successfully with low power dissipation of 1/4 than expected. These results are useful in realizing less power consuming analog circuits.
