摘要
The evaluation method which evaluates the property of the differential die transimpedance amplifier in high order accuracy is offered. Four terminals of differential die transimpedance amplifier 100 are jointed to four ports of 4 port vector network analyzers 101 respectively. S parameter of differential die transimpedance amplifier 100 is measured due to 4 port vector network analyzers 101. S parameter S of differential mode is calculated on the basis of the S parameter whichDD was measured. Z parameter Z of differential mode is calculatedDD making use of the S parameter S of the differential mode whichDD was calculated. Transimpedance property Z of differential die transimpedanceDD amplifier 100 is calculated making use of the Z parameter Z of the differential mode whichT was calculated.
