- Abstract
- A 2-8 GHZ wideband dual-tuned ring voltage-controlled oscillator (VCO) has been designed and fabricated in TSMC 65nm CMOS process. Using a 6-bit digital-to-analog converter (DAC) that provided the V-coarse, the entire frequency range was evenly divided into 64 sub-bands. Next, the oscillation frequency was finely tuned by V-fine to control the strength of the latches in the delay cell of the VCO. In addition, 4-bit latch bank was used in each delay cell to ensure that the K-VCO was scalable. The active silicon area was 0.038 mm(2) and the power consumption was 1.7 and 6.8 mW at 2 and 8 GHz, respectively.
