In order to improve the sensitivity of microarray biosensor
1/f noise
KTC noise and microarray fixed error noise in biosensor are analyzed.And a new correlated double sampling(CDS)circuit is proposed.Noise is effec tively suppressed.The simulation results show that good linear relation between input and output of biosensor is obtained by using CMOS readout circuit based on CDS.
