1. An integrated circuit (IC), comprising:
a voltage-to-current converter circuit having a first voltage input, a second voltage input, a first current terminal, and a second current terminal;
a first transistor having a control input and first and second terminals, the second terminal coupled to the first current terminal;
a second transistor having a control input and first and second terminals, the second terminal of the second transistor coupled to the second current terminal;
a third transistor having a control input and first and second terminals, the control input of the second transistor coupled to the second terminal of the third transistor, the first terminal of the third transistor coupled to a supply voltage terminal;
a fourth transistor having a control input and first and second terminals, the control input of the first transistor coupled to the second terminal of the fourth transistor, the first terminal of the fourth transistor coupled to the supply voltage terminal;
a first resistor coupled between the first terminal of the first transistor and the second terminal of the third transistor;
a second resistor coupled between the first terminal of the second transistor and the second terminal of the fourth transistor;
a first capacitor coupled between the first terminals of the first and second transistors; and
a second capacitor coupled between the second terminals of the first and second transistors.
