For hardware design, RC filter, voltage sensitive resistor and photoelectric isolation method are used to eliminate interference signal in sampling channel and A/D channel.
在硬件方面,采用RC滤波器、压敏电阻、光电隔离等措施,消除了采样通道及A/D通道的干扰信号;
The semiconductor device includes a semiconductor substrate having an active region and a device isolation region defining the active region, and a resistor string formed over the active region.
该半导体器件包 括具有有源区和限定了有源区的器件隔离区的半导体衬底,以及形 成于有源区上方的电阻串。
