A Crystal-Less Clock Generator for Low-Power and Low-Cost Sensor Transceiver With 12.9 MHz-to-3.3 GHz Range, 16.67 ppm/°C Inaccuracy From −25°C to 85°C, and 0.25 μs Settle-Time

A Crystal-Less Clock Generator for Low-Power and Low-Cost Sensor Transceiver With 12.9 MHz-to-3.3 GHz Range, 16.67 ppm/°C Inaccuracy From −25°C to 85°C, and 0.25 μs Settle-Time

This paper proposes the design and implementation of a crystal-less clock generator for low-power, cost-effective sensor transceiver systems. The proposed system integrates a p-poly resistor-based relaxation RC oscillator (RCO), a Fractional-N PLL (W-FPLL) with a wide frequency range and fast settli...
