B1505A C-V Measurements with an SMU as the AC Guard

Frequently Asked Questions (FAQs)SummaryB1505A C-V Measurements with an SMU as the AC GuardQuestionHow to make C-V measurements on a MOSFET using an SMU as the AC Guard with the B1505A.AnswerConnections for Cgs Measurement: •       Max. Frequency is 100 kHz (to make SMU AC guard) •       If higher frequency is required, add ac short capacitor to drain. •       When cable shield is connected to the chassis, it can be used as ac guard                  Connections for Cds Measurement:   Connections for Cdg Measurements: Attachments
