A Low-Noise Wide-BW 3.6-GHz Digital [Formula Omitted] Fractional-N Frequency Synthesizer With a Noise-Shaping Time-to-Digital Converter and Quantization Noise Cancellation

A Low-Noise Wide-BW 3.6-GHz Digital [Formula Omitted] Fractional-N Frequency Synthesizer With a Noise-Shaping Time-to-Digital Converter and Quantization Noise Cancellation

A 3.6-GHz digital fractional-N frequency synthesizer achieving low noise and 500-kHz bandwidth is presented. This architecture uses a gated-ring- oscillator time-to-digital converter (TDC) with 6-ps raw resolution and first-order shaping [abstract truncated by publisher].
