Keywords: | DRNTU::Engineering::Electrical and electronic engineering | Issue Date: | 2012 | Conference: | IEEE International Symposium on Radio-Frequency Integration Technology (2012 : Singapore) | Abstract: | This paper presents a low power 1.2 V, 2.4 GHz low spur, Quadrature PLL synthesizer for IEEE 802.15.4 batteryless transceiver in CMOS 0.18 μm technology. The PLL employs a 1 MHz fully programmable divider with an improved CML 2/3 prescaler, a novel bit-cell for the programmable counters and a novel charge pump with gain-boosted technique to reduce the PLL reference spurs. The PLL consumes a power of 1.85 mW at 1.2 V power supply with the programmable divider consuming only 350 μW. The phase noise of the PLL is -112.77 dBc/Hz at 1 MHz offset and the spurs are -46.2 dB below the carrier and the PLL is successfully tested with the energy harvesting circuit. | URI: | https://hdl.handle.net/10356/98803 http://hdl.handle.net/10220/12776 |
