Description

technical field [0001] The invention relates to the technical field of integrated circuit design, in particular to an On-Off Keying (OOK) demodulator applied to an ultra-wideband radio frequency receiver. Background technique [0002] With the rapid development of integrated circuits and communication technology, high-speed wireless communication technology has become an urgent need for people. Ultra Wide Band (UWB) technology has become one of the most developed communication technologies due to its high speed, low power consumption, low cost, easy implementation, large capacity, strong penetrating power and anti-multipath ability. It is regarded as the key technology of next generation wireless communication. The ultimate goal of any communication system is to receive the transmitted signal and restore the original information, and the UWB communication system is no exception. The demodulator (Demodulator, DM) is the core module of the ultra-wideband radio frequency rece...
