Patent ID: 7907015

Claim:
An electronic device including an operational amplifier, the operational amplifier comprising: an amplifier input stage coupled with a first output node (V 1 ) to an amplifier output stage; a compensation capacitance (CM) connected between an output node (Vout) of the amplifier output stage and the first output node (V 1 ) of the amplifier input stage thereby operating as a compensator for stabilizing the operational amplifier, the compensation capacitance (CM) providing a parasitic diode (D) drawing a first leakage current (Ileak 1 ) from the first output node (V 1 ) of the amplifier input stage; a leakage current compensation circuit (M 6 , M 7 , M 8 , M 9 , I 2 , I 2 ′) being coupled to the first output node (V 1 ) of the amplifier input stage and coupled to a second output node (V 3 ) of the amplifier input stage for drawing a first current (I 5 ) from the first output node (V 1 ) and a second current (I 3 ) from the second output node (V 3 ), wherein the leakage current compensation circuit is adapted such that the second current (I 3 ) is greater than the first current (I 5 ) by an amount corresponding to the first leakage current (Ileak 1 ).
