1. An electronic circuit comprising:
a digital-to-analog converter (DAC) having first and second terminals; and
a compensation circuit including:
a capacitor having first and second terminals, the first terminal of the capacitor coupled to the first terminal of the DAC; and
a first transistor having a first current path terminal coupled to the second terminal of the capacitor, and having a control terminal coupled to the second terminal of the DAC, wherein the DAC comprises:
a second transistor having a first current path terminal coupled to the second terminal of the DAC,
a third transistor having a first current path terminal coupled to the second terminal of the DAC,
a fourth transistor having first and second current path terminals, the second current path terminal coupled to the first terminal of the DAC; and
a fifth transistor having a first current path terminal coupled to the second current path terminal of the fourth transistor, and having a second current path terminal coupled to the first current path terminal of the second transistor, and to the first current path terminal of the third transistors.
