The Digital Frequency Discriminator (DFD) with delay lines has been commonly used at instantaneous frequency measurement systems. However, the main limitation of this type DFD is size because multi-delay lines are necessary to achieve the high resolution and accurate detection. Therefore, in recent years, the digital counting techniques without delay
lines have been proposed for the DFD. The digital counting technique requires a high frequency clock signal in order to achieve the high resolution and accurate detection. In this paper, we present a DFD with a time to digital converter (TDC) without any delay-lines and high frequency clock signals. In this method, the DFD includes a frequency divider, a TDC and a binary counter. The input signal is divided by N in the frequency divider. The TDC detect the all of the N divided periods in the measured time and the binary counter detects the number of periods during the measurement time. The frequency information
can be calculated with TDC output, the output of binary counter, and the N number. The circuit was fabricated in 0.18-um SiGe-BiCMOS process. It is achieved that the measured absolute error is below 0.17MHz and measured relative error is below 0.72MHz-rms at the range 0.3MHz to 2GHz band. |
