- 초록
- A low-power 50-GHz LC-VCO has been presented. Throughout EM analysis, an inductor having a quality factor of 14.3 was implemented with a microstrip line. The analyzed characteristics of a MOS varactor limit the LC tank performance due to its low quality factor. In order to overcome the LC tank performance and operate at low-power consumption, the negative transconductance stage was evaluated in various ways and found at the condition of the optimized MOSFET size and bias point. The proposed VCO was implemented in a 65-nm CMOS technology. The measurement results show a frequency range of 48.61 GHz ~ 50.84 GHz and an output power of-10 dBm. The required VCO current is about 4.7 mA from a 0.7 V supply.
