The invention pertains to a latch circuit (10) comprising a sensing arrangement (12) with one or more sensing transistors (T 1, T 2 ) adapted to sense an input signal (D, D n ) and to provide a first signal based on the sensed input signal (D, D n ), and a sensing arrangement switch device (16) connected or connectable to a first current source (18), the sensing arrangement switch device (16) being adapted to switch on or off a current to the one or more sensing transistors (T 1, T 2 ) based on a first clock signal (CLK). The latch circuit (10) further comprises a storage arrangement (14) with one or more storage transistors (T 3, T 4 ) adapted to store the first signal and to provide a second signal based on the first signal, and a storage arrangement switching device (20) connected or connectable to the first current source (18) or a second current source, the storage arrangement switching device (20) being adapted to switch on or off a current to the storage transistors (T 3, T 4 ) based on a second clock signal (CLK n ), as well as a tuning arrangement (24) connected or connectable to a temperature sensor (106, 108), the tuning arrangement (24) being adapted to bias a current of the sensing arrangement (12) and/or the storage arrangement (14) based on a temperature signal provided by the temperature sensor (106, 108). The invention also pertains to a flip-flop circuit with two or more latch circuits and a frequency divider (100) comprising at least one latch circuit (10) as described. |
