An RF low phase noise voltage-controlled oscillator is implemented with micromachined IC-compatible variable capacitors and three-dimensional coil inductor. Unlike conventional on-chip passive devices, the micromachined variable capacitors achieve a high-Q value above 60 at 1 GHz with a 15% tuning r
## Abstract This article proposes a wide tuning voltageβcontrolled oscillator (VCO) by employing a transformerβbased LCβtank and is fabricated in a TSMC 0.18 ΞΌm CMOS process with 1.5 V supply voltage. We choose decoupling effect to decrease primary and secondary inductances and then decrease qualit
