    • A scan flip-flop circuit includes a pulse generator, a dynamic input unit and a latch output unit. The pulse generator generates a pulse signal which is enabled in synchronization with a rising edge of a clock signal in a normal mode, and is selectively enabled in synchronization with the rising edge of the clock signal in response to a logic level of a scan input signal in a scan mode. The dynamic input unit precharges a first node to a power supply voltage in a first phase of the clock signal, selectively discharges the first node in the normal mode, and discharges the first node in the scan mode. The latch output unit latches an internal signal provided from the first node to provide an output data, and determines whether the output data is toggled based on the clock signal and a previous state of the output data.

    • Provided is a discrete signal finite impulse response (FIR) filter and a filter set in which a plurality of FIR filter units are connected in a cascade structure to remove down-sampling by decimation, in order to improve the attenuation characteristics of a FIR filter, such as, for example, a switched capacitor filter. The FIR filter includes a clock generator generating a plurality of clock signals that are different from each other; and N+2 sub blocks each including N sample storage units, each sample storage unit storing a received sample. Each sub block being in a state among a number of possible states including N charging states for storing the received sample, a transfer state for outputting the stored sample and a reset state for operation initialization. The N charging states, the transfer state and the reset state are changed sequentially in response to the clock signals.
