Latch circuit, flip-flop circuit and frequency divider |
摘要 |
The invention pertains to a latch circuit comprising a sensing arrangement with one or more sensing transistors adapted to sense an input signal and to provide a first signal based on the sensed input signal, and a sensing arrangement switch device connected or connectable to a first current source, the sensing arrangement switch device being adapted to switch on or off a current to the one or more sensing transistors based on a first clock signal. The latch circuit further comprises a storage arrangement with one or more storage transistors adapted to store the first signal and to provide a second signal based on the first signal, and a storage arrangement switching device connected or connectable to the first current source or a second current source, the storage arrangement switching device being adapted to switch on or off a current to the storage transistors based on a second clock signal, as well as a tuning arrangement connected or connectable to a temperature sensor, the tuning arrangement being adapted to bias a current of the sensing arrangement and/or the storage arrangement based on a temperature signal provided by the temperature sensor. The invention also pertains to a flip-flop circuit with two or more latch circuits and a frequency divider comprising at least one latch circuit as described. |
