<p>A self-adaptive output buffer ( 130 ) for an output terminal of an electronic circuit ( 100 ) suitable to be connected to a load ( Cload ) is proposed. The self-adaptive output buffer includes means for sensing ( 205 ) an indication of the capacitance of the load and means for driving ( 210 ) the load according to the sensing, wherein the means for sensing ( 205 ) includes capacitive means ( C S1 ) with a preset capacitance, means ( P S1 , N S1 ) for charging the capacitive means to a preset voltage, means for coupling the charged capacitive means with the load, and means for measuring ( 230 , 225 ) a measuring voltage at the capacitive means due to a charge sharing between the capacitive means ( C S1 ) and the load ( Cload ).</p> |
