Abstract

__Biochips of 256 micro-ISFETs were made with 0.18 um CMOS processes towards pH based DNA sequencing. We implemented a pulse voltage biasing method to improve pH sensing performance. Compared to pulse DC biasing, pulse AC can achieve much better stability and higher sensitivity.

脉冲交流偏置下微阵列isfet的pH传感性能改进

__256个微型isfet的生物芯片采用0.18 um CMOS工艺，用于基于pH的DNA测序。我们实现了一种脉冲电压偏置方法来提高pH值传感性能。与脉冲直流偏置相比，脉冲交流可以获得更好的稳定性和更高的灵敏度。
