3)
External bypass capacitors should be placed as close to the package as possible.
Dual biasing sequence required:
a. Turn-on Sequence: Apply V_g1 = -2.5V, V_g2 = -2.5V, followed by V_d1 = V_d2 = 7V, lastly increase
V_g1 & V_g2 in sequence until required I_d1 and I_d2 is obtained.
b. Turn-off Sequence: Turn off V_d1 & V_d2, followed by V_g1 & V_g2
Demonstration board available upon request.
