Abstract:Frequency standard comparison measurement has important practical significance for the rational use of frequency standard in engineering. This paper was devoted to the study of frequency standard comparison measurement based on classical dual mixing time difference method. However, in the actual system design and implementation, the commonly used counter was discarded and the phase difference was measured by a digital signal processing method based on Field Programmable Gate Array (FPGA). A miniaturized 10 MHz… Show more
“…A miniaturized frequency standard comparator based on FPGA was presented. The noise floor of the analyzed comparator was better than 7.50 * 10 −12 (1/s) [6]. A low-ripple switched-capacitor DC-DC Converter with parallel low-dropout regulator was proposed.…”
