Bias Sequence and Gain Control
Optimum performance is achieved using sequential bias. At maximum gain (V_C1, V_C3), and V_C2 are set at -4V and V_G2 is set at
-0.4V. (V_C1, V_C3), V_C2 and V_G2 are biased in sequence. The first dynamic range is achieved by setting (V_C2 at -4V and V_G2 at
-0.4V) and varying (V_C1, V_C3) over the (-4 to -1V) range as shown in the table below. Similarly, the second dynamic range is
achieved by setting (V_C1, V_C3) at -1V, V_G2 at -0.4V and varying V_C2 over the (-4 to -0.3V) range. Finally, the third dynamic range
is achieved by setting (V_C1, V_C3) at -1V, V_C2 at -0.3V and varying V_G2 over the (-0.4 to -1V) range.
