Figure 15. Si321x Optional Equivalent Q5, Q6 Bias Circuit
The subcircuit above can be substituted into any of the ProSLIC solutions as an optional bias circuit for Q5 and Q6.
For this optional subcircuit, C7 and C8 differ in voltage and capacitance from the standard circuit. R23 and R24 are
additional components.
