Claim 0:
1. A semiconductor device comprising:
a first source follower comprising a first transistor and a second transistor;
a second source follower comprising a third transistor and a fourth transistor;
a fifth transistor;
a capacitor; and
a comparator,
wherein one of a source and a drain of the first transistor and one of a source and a drain of the second transistor are electrically connected to one of a source and a drain of the fifth transistor,
wherein one of a source and a drain of the third transistor and one of a source and a drain of the fourth transistor are electrically connected to an inverting input terminal of the comparator, and
wherein the other of the source and the drain of the fifth transistor is electrically connected to one terminal of the capacitor and a non-inverting input terminal of the comparator.
