Problems solved by technology

[0003] For portable products or energy-saving applications, the receiver often enters a disabled (or sleep) state when not in use, and the system startup time will affect the product response time
[0004] When the time constant of the filter is too large, it will cause the receiver's system start-up time to be longer, and indirectly slow down the product response time

Embodiment Construction

[0014] figure 1 A schematic diagram of a receiver 100 according to an embodiment of the invention is shown. Such as figure 1 As shown, the receiver 100 may include: an antenna 110 , a radio frequency circuit (RF circuit) 120 , a demodulation circuit (demodulation circuit) 130 , and a data slicer (data slicer) 150 . The antenna 110 is configured to receive a radio frequency signal SR. The antenna 110 may be a planar inverted F antenna, a monopole antenna, a loop antenna, a helical antenna or a chip antenna. The radio frequency circuit 120 may include a low-noise amplifier, a mixer and a local oscillator (not shown), and is used for generating an intermediate frequency signal SM according to the radio frequency signal SR. The demodulation circuit 130 can be used to demodulate the intermediate frequency signal SM to generate a demodulated signal SD.

[0015] The data slicer 150 may include: a filter 152 , a comparator 154 , a switch 156 , and a delay generator 158 . The filt...

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.

Description

technical field [0001] The present invention relates to a receiver, and more particularly to a receiver that can be used to reduce system start-up time. Background technique [0002] In a conventional receiver, a time constant of a filter is determined according to a data rate of a radio frequency (RF) signal. The slower the data rate, the larger the filter time constant must be set. [0003] For portable products or energy-saving applications, the receiver often enters a disabled (or dormant) state when not in use. At this time, the system startup time will affect the product response time. [0004] When the time constant of the filter is too large, the system start-up time of the receiver will be longer, and the reaction time of the product will be slower indirectly. [0005] In order to solve the above problems, a receiver that can reduce the system start-up time is required. Contents of the invention [0006] The present invention provides a receiver for reducing th...
