Abstract: The bus switch with back gate control circuit includes: an NMOS transistor coupled between a first port and a second port; a PMOS transistor coupled in parallel with the NMOS transistor; a first blocking device coupled between the first port and a control node of the PMOS transistor; a second blocking device coupled between the second port and the control node of the PMOS transistor; a first pull-down device coupled to a back gate of the NMOS transistor; and a second pull-down device coupled to the back gate of the NMOS transistor, wherein the pull down device is controlled by a power supply node and the control node of the PMOS transistor.

Abstract: The pass-gate circuit with backgate pull-up includes: a pass-gate transistor coupled between a first port and a second port; a backgate pull-up transistor coupled between a back gate of the pass-gate transistor and a gate of the pass-gate transistor; a first MOS transistor coupled between a first port and the gate of the pass-gate transistor; and a second MOS transistor coupled between a second port and the gate of the pass-gate transistor.
