Abstract

Engineering Engineering, Electrical & Electronic Science & Technology Technology Telecommunications
A low-power fractional-N synthesizer is designed for direct modulation transmitter at 2.40-2.50GHz range using standard 0.18 mu m CMOS. The synthesizer is fully implemented on-chip for integrated low data rate Wireless Sensor Network (WSN) application. The data rate is as low as 10kbit/s. Phase noise of -93dBc/Hz at 600kHz offset is 2 measured for the synthesizer. The active area is 0.8x0.8mm with total power of 8.0mW from a single 1.8V supply.
