Abstract
A current-mode D latch includes a first load element, a second load element, a first bias current source, a first switch transistor, a second switch transistor, a first stage circuit and a second stage circuit. The first switch transistor is controlled by an inverted reset signal. The second switch transistor is controlled by a reset signal. When an inverted clock signal is in a first level state and the reset signal is inactive, the first input signal is converted into the first output signal and the first inverted input signal is converted into the first inverted output signal by the first stage circuit. When a clock signal is in the first level state and the reset signal is inactive, the first output signal and the first inverted output signal are maintained by the second stage circuit.
