Claim 0:
1. A circuit with reliable margin configuration, comprising:
a main circuit comprising a first node;
a first auxiliary circuit coupled to the first node; and
a second auxiliary circuit coupled to the first node and a control signal;, wherein:
when the first auxiliary circuit is on, the second auxiliary circuit is on or off according to whether the control signal is of a first level or a second level;
when the first auxiliary circuit and the second auxiliary circuit are both on, the first auxiliary circuit and the second auxiliary circuit jointly cause an operation parameter of the main circuit to be a first value;
when the first auxiliary circuit is on and the second auxiliary circuit is off, the first auxiliary circuit causes said operation parameter to be a second value different from the first value; and
an operation margin of the main circuit covers a range between the first value and the second value.
