Abstract

This paper presents a wide-range low-power fully integrated fractional-N PLL. The PLL consumes 1.13mW to 1mW at 1.2V supply voltage, in a wide frequency range from 1.7GHz to 2.5GHz. It achieves up to -115 dBc/Hz phase noise at 1MHz offset and up to 2.5 degrees RMS phase error. The settling time is 40μs. The PLL is implemented in 90nm CMOS. The PLL can be used for low power wireless body area network (WBAN) and wireless sensor network (WSN) applications at 433MHz, 900MHz and 2.4 GHz.
