Abstract

A flip-flop circuit may include: a latch unit configured to latch an input signal in response to a clock signal; and a timing control unit configured to delay a signal provided from the latch unit by a predetermined time regardless of the clock signal.

Claims (13)

1. A flip-flop circuit comprising:

a latch unit configured to latch an input signal in response to a clock signal; and

a timing control unit configured to generate a delay signal by delaying a signal provided from the latch unit by a predetermined time regardless of the clock signal and output the delay signal as a final output data of the flip-flop circuit,

wherein the timing control unit comprises a transmission switching element configured to be driven by first and second bias voltages and delay the output signal of the latch unit.

2. The flip-flop circuit according to claim 1 , further comprising:

an input unit configured to latch an initial input signal in response to the clock signal; and

a driving unit configured to latch the signal provided from the input unit in response to the clock signal and output the latched signal as the input signal.

3. The flip-flop circuit according to claim 2 , wherein the input unit latches the initial input signal in synchronization with a first phase of the clock signal, the driving unit latches a signal provided from the input unit in synchronization with a second phase of the clock signal, and the latch unit latches the input signal in synchronization with the first phase of the clock signal.

4. A semiconductor apparatus comprising a plurality of flip-flop circuits coupled in series,

wherein each of the flip-flop circuits comprises:

a latch unit configured to latch an input signal in response to a clock signal; and

a timing control unit configured to generate a delay signal by delaying a signal provided from the latch unit by a preset time regardless of the clock signal and output the delay signal as a final output data of the flip-flop circuit,

wherein the timing control unit comprises a transmission switching element configured to be driven by first and second bias voltages and delay the output signal of the latch unit.
