As a special-purpose computer system to solve specific problems, the embedded system is very suited to be implemented by the FPGA. However, without fixed hardware architecture, the FPGA-based computing system is mostly a mixture of hardware and software. This kind of system is difficult to design because hardware and software are developed using quite different models of computation. To handle this...
In this paper, we present a high accurate frequency-temperature compensation method for temperature compensated crystal oscillators (TCXO) which can achieve 0.1 ppm frequency stability over a wide temperature range from -25degC to 85degC by using 1-bit successive approximation differentiated interpolation. By applying a frequency-temperature compensated digital binary word to a digital frequency synthesizer,...
