Components

Note: V_GS will be larger with the body effect.

Procedure

• Note that PMOS body pin 14 and the NMOS drain terminal are at ground. Set RS and VSSinit from NMOSparsub.vi. Run NMOSgamsub.vi with VSB = 0 V and 3 V to verity that circuit is functioning properly. Note the change in the VGS range for the larger VSB. VSSinit is adjusted automatically for larger values of VSB, to obtain, approximately, a starting ID of about 50 μA. Default and save the Front Panel to save VSSinit.
