A 2.4 GHz Voltage Controlled Oscillator
نویسنده
چکیده
Voltage controlled oscillators are essential building blocks in communication systems and are used as local oscillators to up and down-convert signals in an RF mixer. Despite the continuous improvement in the state of the art of CMOS VCO’s, they still remain the most critical blocks of RF transceivers. The most important parameters of a VCO are phase noise, power consumption and frequency tuning ranges. The monolithic integration of all components of a VCO is also very challenging. A 2.4 GHz voltage controlled oscillator (VCO) has been designed in a standard 0.25m CMOS process.
