  • Circuit module with reliable margin configuration
    Patent number: 11935581
    Abstract: A circuit module with reliable margin configuration, may include a main circuit, a first auxiliary circuit and a second auxiliary circuit. When the first auxiliary circuit is on, the second auxiliary circuit may be on or off according to whether a 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 may 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 may cause the operation parameter to be a second value. An operation margin of the main circuit may cover a range between the first value and the second value.
