Low Voltage Operation Analog Signal Processing Circuits for Complex Signal Processing

设计并制作了可在1V或0.5V电源下工作的全差分放大器。它们的增益分别为80 dB和35 dB，带宽分别为10 HMz和30 MHz，功耗分别为200μW和300μW。作者找到了一类不需要共模抑制的三相有源复合滤波器结构，并成功地制作了测试芯片，其功耗比预期低1/4。这些结果对实现低功耗模拟电路有一定的参考价值。

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.
