P9.2. DC Evaluation of the Single-Power-Supply Differential Amplifier

Components RD1 = RD2 = RD Rs = RD/2 VD ≈ VDD/2 – VSG For Chan0_out = 10 V: 100 μA<ID <400 μA (Choose One) RG <100 kΩ Match the gate resistors on each side to obtain VG = VDD/2. On a given side, the resistors must be equal, but can be different on opposite sides. Procedure After completing the circuit connections, open DC.vi. Set Chan0_out = 10 V and run the VI. DC.vi scans Chan1_out to balance the circuit (i.e., to set VD1 = VD2 within 20 mV). Try Chan0_out in the range 5 ...
