A CMOS LC voltage-controlled oscillator (VCO) capable of covering both the Ku and Ka bands is presented. The Ku-band frequency source is generated from a low-noise cross-coupled LC VCO. A PMOS push-push frequency doubler, together with the inductor of the low-band LC VCO, is adopted to boost the low Ku-band toward high Ka-band. This proposed VCO is implemented in a standard 0.18 μm CMOS with 1.35 V supply voltage. The dual-band VCO consumes a small active area of 0.49 mm × 0.2 mm and low DC… CONTINUE READING
