- In this paper, an ultra-fast and miniaturized digital instantaneous frequency measurement (DIFM) system is proposed. Based on the high speed clocked comparator and high performance Field Programmable Gate Array (FPGA), the system is constructed. High speed clocked comparator with only 120 ps propagation delay is adopted to replace ADC to do single bit sampling, and FPGA GTH transceivers receive the high speed bits stream. Then the digital processing is done in the FPGA with enjoying shorter processing time comparing with analog IFM. It takes less than 150 ns to output the frequency. Comparing traditional analog with digital method, this design has a smaller area, a higher calculation speed and less power consumption. The design is flexible to reconfigure , easy for operation and it is much more reliable. Our designed IFM receiver has applied to a radar counterwork system.
