摘要：
A new high resolution digital frequency detector architecture based on multiphase ring oscillator is proposed, and it uses the time resolution of fast-operating deep sub-micron MOS transistor. The proposed DFD is implemented with 65nm CMOS technology. The measured frequency resolution is amount to 75dBc with 10.2MHz input signal. Fabricated digital frequency detector draws about 4mA in 1.2V supply voltage.
