| Abstract: | A wide tuning range gated varactor for radio frequency (RF) applications is described in this paper. The gated varactor is a three terminal device. The third terminal helps achieve an improved tuning range. The measured tuning range of the varactor exceeds ±50%. The new device can be implemented with standard CMOS process without any post-processing. A 2 G Hz prototype VCO is implemented using the new varactor in a 0.35 μm CMOS process. The VCO achieved a sensitivity of 220 M Hz/V. |
