P2.2. NMOS Common-Source Amplifier with Resistor Gate Bias Circuit

Components


Programming Exercise 2.2

  • Save a copy of AmpP2.1.vi (your name) and give it a new name.

  • As in the example (below), use three While Loops to send Chan0_out and receive on Chan0_in and Chan1_in. Note that the index “i” of a loop on the left is connected to the border of the following Loop to establish the proper order of execution of the program.

  • Provide Digital Indicators for VGS and VDS.

Procedure

  • Run AmpP2.2.vi with VDD set at 6 V to obtain VGS of about 2 V (due to RG1 ≈ 2RG2). Rerun and adjust VDD to obtain VDS equal to about one-half of VDD. Note that decreasing VDD raises VDS toward VDD. Default and save the Front Panel for the Mathcad evaluation.
