Title:
LEVEL SHIFT CIRCUIT AND POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/107655
Kind Code:
A1
Abstract:
This level shift circuit comprises: first and second input transistors that are configured to be complementarily turned on/off in accordance with a control signal; first and second switches that are configured to supply electric currents to the first and second input transistors, respectively, when on; first and second clamp elements that are connected between the first and second input transistors and the first and second switches; an output signal generation unit that is configured to generate, on the basis of the on/off state of the electric current supply from the first and second switches to the first and second input transistors, an output signal obtained by level-shifting the control signal; and first and second current adjustment units that are configured to adjust, on the basis of first and second feedback signals fed back from the output signal generation unit, the values of the electric currents supplied to the first and second switches.
