Abstract
A 2.4-GHz half-sine shaping O-QPSK transmitter (TX) which supports IEEE 802.15.4 standard is reported. This TX employs a RF phase modulator which incorporates a semi-digital FIR filter for waveform shaping. Fabricated in a 0.18-μm CMOS process, the TX, including a PLL, draws 10 mA from a 1.5-V supply and delivers an output power of −3 dBm. It achieves an EVM of 6.2% when operating at 2-Mcps chip rate.
