Abstract :
This paper presents how to design a RF transmitter with only two CMOS digital inverters. The RF oscillator is controlled by a fundamental mode quartz crystal operating in load resonance. The RF amplifier consists of one CMOS inverter, having the capability to produce an output power of 10 mW. An 8 elements matching and filtering network has been designed in order to match the CMOS transmitter´s output to a 50 Ω antenna, and to comply with the European telecommunication regulations.
