Abstract :
We have developed a 27 GHz tuned amplifier and 52.5 GHz voltage-controlled oscillator (VCO) using 0.18 μm CMOS. We used LRL calibration to extract accurate S-parameters for an intrinsic transistor with a microstrip line (MSL) structure consisting of metal1 and metal6. With this technique, we obtained a 17 dB gain and 14 dBm output power at 27 GHz for the tuned amplifier. We also obtained an oscillation frequency of 52.5 GHz with phase noise of -86 dBc/Hz at a 1 MHz offset. These results indicate that our proposed technique is suitable for CMOS millimeter wave design.
