Abstract
A receiver for reducing a system start-up time includes an antenna, an RF (Radio Frequency) circuit, a demodulation circuit, and a data slicer. The data slicer includes a filter, a comparator, a switch, and a delay generator. The filter filters a demodulated signal so as to generate a threshold level. The comparator has a positive input terminal for receiving the demodulated signal and a negative input terminal for receiving the threshold level. The comparator compares the demodulated signal with the threshold level so as to generate a digital signal. The switch is coupled between the positive input terminal and the negative input terminal. The delay generator determines whether or not to close the switch during a delay time according to an enable signal.
