In this paper,a portable 2.42 GHz transmitter for wireless communication systems,with 8dBm output power and small size is proposed.Several novel features exist in this transmitter.First,power consumption and output are balanced by introducing a differential oscillator with input signal controlled biasing,which acts as both a carrier generator and an OOK modulator.Then,power consumption of the transmitter is reduced by the OOK modulated signal via switching the oscillator and the power amplifier at the same time.Furthermore,the area size is also reduced by a class-AB power amplifier,which uses the PCB antenna as the resonance inductance.With these features,the total chip area is reduced to 670μm×740μm(In a 0.18μm CMOS process). In this paper, a portable 2.42 GHz transmitter for wireless communication systems, with 8dBm output power and small size is proposed. Sevice novel features present in this transmitter. First, power consumption and output are balanced by introducing a differential oscillator with input signal controlled biasing , which acts as both a carrier generator and an OOK modulator. Chen, power consumption of the transmitter is reduced by the OOK modulated signal via switching the oscillator and the power amplifier at the same time. More than that, the area size is also reduced by a class-AB power amplifier, which uses the PCB antenna as the resonance inductance. These features, the total chip area is reduced to 670 μm × 740 μm (In a 0.18 μm CMOS process).
