Abstract:
A gate driving circuit may include: a bias unit receiving an input signal having preset high and low signal levels, including a first N-MOSFET turned on in the case in which the input signal has the high level and a first P-MOSFET turned on in the case in which the input signal has the low level, and supplying bias powers by the turning-on of the first N-MOSFET and the first P-MOSFET; and an amplifying unit including a second N-MOSFET turned on by receiving the bias power supplied from the first N-MOSFET in the case in which the input signal has the high level and a second P-MOSFET turned on by receiving the bias power supplied from the first P-MOSFET turned on in the case in which the input signal has the low level and providing a gate signal depending on the turning-on of the second N-MOSFET and the second P-MOSFET.
