Abstract

This paper presents design of a transmitter operating in 315 MHz frequency with OOK modulation for short-range wireless sensor networks. In this design, a ring oscillator is used to generate low frequeny oscillation, which is multiplied using an edge combiner up to carrier frequency. The output power is guaranteed by an inverter based class-D power amplifier. The main components are designed using MOS active elements, the frequency of the oscillator is low, reducing chip area and power consumption. The transmitter is fabirated on 0.18 μm CMOS technology, it achieves -8.7 dBm output power, consumes 1.7 mW with 0.075 mm² chip area.

Keywords
