Abstract
In this paper, an inductor-less, high frequency tuning range and low power CMOS voltage controlled oscillator (VCO) is presented. The VCO can be implemented in 0.18 µm CMOS, with 1.8 V supply voltage. By using a novel structure, a high frequency tuning range, low phase noise and low power consumption VCO, is obtained. In order to increase the frequency tuning range, an active inductor is used. In addition, deep triode region transistors are employed to enhance the swing of the output voltage. By using the results of simulation with HSPISE software, the tuning range, phase noise and power consumption are 5.49-9.6 GHz, -146 dBc/Hz and 5.99 mW, respectively.
