Patent number: 10685272Abstract: An oscillation maintenance circuit with comparator-based pulse generation is provided. By sampling an RF signal and controlling a pulse generation circuit to generate a pulse signal of the same frequency as the RF signal, a switch unit is controlled to be ON/OFF at a same frequency as the RF signal, achieving synchronization between change of the current injection and the RF signal. Thus, the oscillation frequency is not affected by current injection, ensuring the FSK communication performance. At the same time, two comparators are respectively compared with two reference voltage levels to obtain an output pulse signal, and the reference voltage levels can be adjusted according to practical requirements, so that the switch-on point of time and current injection time duration are adjustable, maximizing the efficiency of current injection, resulting in simple circuit structure, low power consumption, and increased communication distance of an HDX passive RFID transponder.Type: GrantFiled: October 10, 2017Date of Patent: June 16, 2020Assignee: EXCELIO TECHNOLOGY (SHENZHEN) CO., LTD.Inventors: Qianwen Zhang, Patrick Bian Wu, Fuqiang Han
