Controlling current flow between nodes with adjustable back-gate voltage
Embodiments of the present disclosure provide a circuit structure including: a first transistor having a gate terminal, a source terminal, a drain terminal, and a back-gate terminal electrically coupled to an adjustable voltage source. The gate terminal of the first transistor is electrically coupled to a first node having a first bias voltage. A second transistor has a gate terminal, a source terminal electrically coupled to the drain terminal of the first transistor, a drain terminal, and a back-gate terminal electrically connected to the adjustable voltage source. The gate terminal of the second transistor is electrically coupled to a second node having a second bias voltage. The adjustable voltage source is selectable between a first voltage and a second voltage to control a threshold voltage of the first transistor and a threshold voltage of the second transistor.
