This common-mode biasing can be achieved using the on-chip differential amplifier, further reducing the external signal conditioning requirements. 此共模偏置可利用片内差分放大器来实现,从而可进一步降低外部信号调理要求。
In order to solve those problems, this paper presents a signal conditioning method with the averaged value of the first harmonic and proposes an intermitted exciting mode. 为了解决这些问题,本文提出了基波平均值的信号调理方法和间歇激磁方法,检定结果表明了该种方法的有效性。
