1. An integrated circuit comprising:
a latch circuit comprising a latch and a sensing transistor coupled to the latch; and
a compensation circuit coupled to the sensing transistor,
wherein the sensing transistor comprises a gate terminal coupled to a sensing node and an additional terminal coupled to the compensation circuit, and
wherein the compensation circuit is configured to apply a control voltage to the additional terminal to compensate for a variation of a threshold voltage of the sensing transistor.
