Loop control coefficients in a buck converter

A comparator, comprising:

• a first transistor including a first gate, a first source, and a first drain, the first gate configured to receive a feedback signal;
• a second transistor including a second gate, a second source, and a second drain, the second gate configured to receive the feedback signal and wherein the second drain is connected to the first drain;
• a third transistor including a third gate, a third source, and a third drain;
• a fourth transistor including a fourth gate, a fourth source, and a fourth drain, the fourth gate configured to receive the reference signal and wherein the fourth drain is connected to the third drain;
• a first switch including a first terminal and a second terminal, the first terminal connected to the second gate and the second terminal connected to the third gate;
• and
• a second switch including a third terminal and a fourth terminal, the third terminal connected to the third gate and the fourth terminal connected to the fourth gate.

A buck converter, comprising:

• a high side power transistor configured to, when ON, connect an inductor to an input signal;
• a low side power transistor configured to, when ON, connect the inductor to ground;
• and
