- Figure 1. The simplest case of logic signal totem pole drive - direct connection works if V++ <= VL
- Figure 2. AC coupling can solve the problem of positive rail voltage mismatch if the control signal runs continuously
- Figure 3. Ditto for AC coupling and negative rail mismatch, too
- Figure 4. "Grounded" gate Q3 maintains C1 charge when logic signal stops
- Figure 5. Grounded gate Q4 shifts logic signal to negative rail referred C2 and Q2
