Abstract:
1. A driving circuit comprising: a driving section for buffering an input signal at an input node, and outputting an amplified signal to an output node; a rising edge detector for detecting a rising edge of the input signal and outputting a first detection signal having a pulse width corresponding to ambient temperature; and a first transistor connected between the output node and a power supply potential node, and controlled to be conductive according to the first detection signal, wherein said driving section comprises a first inverter receiving the input signal at the input node, and a second inverter receiving an output of the first inverter and having an output connected to the out node, and said rising edge detector comprises a third inverter receiving the input signal at the input node, and a NAND gate having one input receiving the input signal at the input node, having another input receiving an output of the third inverter and having an output connected to a gate of the first transistor.
