A True Single Phase Clock (TSPC) pre-charge based flip-flop is provided. The flip-flop includes a scan section, a master section, and a slave section. The scan section receives a scan enable signal, a scan input signal, a clock signal, and feedback data from the master section, and outputs an internal signal to the master section based on the scan enable signal, the scan input signal, the clock signal, and the feedback data. The master section is coupled to the scan section and receives the internal signal and a data input, and outputs a master feedback signal to the slave section based on the internal signal, the data input, and the feedback data. The slave section is coupled to the master section and generates an output by latching the master feedback signal received from the master section according to the clock signal. The clock signal is a True-Single-Phase-Clock (TSPC).
