Abstract

The field of high-frequency circuit design is receiving significant industrial attention due to variety of radio frequency and microwave applications. This work proposes the low power, low phase noise and low phase error quadrature voltage controlled oscillator (LP3 - QVCO) for wireless receiver applications. An enhanced investigation and design of the low power, low phase noise and low phase error quadrature voltage controlled oscillator (LP3 - QVCO) is carried out in comparison to conventional LC- QVCO. The design, implementation and characterization of the complementary LP3 - QVCO is carried out with the integration of 40 S1 source damping resistor (Rdmp), tail biasing resistor (Rtait) and multifinger gate width configuration of the pMOS varactors and 50 S1 impedance of common drain output buffers. The LP3 - QV CO implementation is carried out using 0.18 p,m, 6 metal, 1 poly, 1.8 V and 0.13 p,m, 8 metal, 1 poly, 1.2 V deep sub-micron CMOS and RF CMOS process technologies. The three different designs with the center frequencies of 2.8 GHz, 3.1 GHz and 3.8 GHz are implemented using 0.18 p,m CMOS and RF CMOS process technology. The remaining four designs with the center frequencies of 4.35 GHz and 5 GHz are implemented using 0.13 p,m RF CMOS process technologies. The LP3 - QVCO design exhibit the measured phase noise of -110.13 dBc/Hz and -108.54 dBc/Hz at the offset frequency of 1 MHz, with multifinger gate width configuration of pMOS varactor (3.125 p,m x 64 = 200 p,m) and (8 p,m x 25 = 200 p,m), respectively. The phase noise im provement of 1.63 dB is achieved in LP3 - QVCO design implemented with (3.125 I'm x 64 = 200 I'm) mult.ifinger gate width configuration of pMOS varactor in comparison to (8 f.tm x 25 = 200 f.tm). The measured center frequency of the LP3 - QVCO is 4.35 GHz with the frequency tuning range of 4.21 GHz to 4.44 GHz. Both LP3 - QVCO core power dissipation is 3.36 m W from 1.2 V de power supply. The measured phase error is less than 0.2'. The calculated figure of merit (FOM) is -177.6 dBc/Hz. The symmetrical spiral inductor is also used with patterned ground shield (PGS). The quality (Q) factor of inductor is 18.6 and is implemented using 0.13 f.tm RF CMOS process technology.
