Incidentally, neither of these circuits will work, since in both cases the base of a lower transistor is connected to the base of an opposite side upper transistor. In the left circuit this clamps the base of the lower transistor to V+ - 0.7V, and for the right circuit its upper transistor's base to +0.7V.
Is this correcting ?You would use the left circuit with P-MOSFETs on the top and N-MOSFETs on the bottom.
Using all N-MOSFETs, as the right circuit would require, would not sufficiently turn on the top transistors.
Note that, for the left circuit, add 1kΩ pullup resistors from each gate connection to V+.
You will need protection circuitry for the gate voltages to keep their Vgs below about 15V for typical MOSFETs (see data sheet), if the total V+ and V- voltages total more than 15V.
This can be as simple as some added voltage divider resistors at the gate to source of each transistor.
No, I'm afraid not.Is this correcting ?
