Abstract Details

2015, Master of Science in Electrical Engineering (MSEE), Wright State University, Electrical Engineering.
This thesis presents wide tuning range in-phase and quad-phase (I/Q) output digital control oscillator (DCO) and voltage control oscillator (VCO) and a simple high performance phase frequency detector (PFD) in 90 nm CMOS technology with 1.2 V power supply. The designed I/Q output DCO has an operating frequency range from 1.1-8.2 GHz with high resolution and wide linearity by using a novel skew delay structure. At 2.02GHz oscillation frequency, the measured phase noise of I/Q output DCO is -90.43dBc/Hz at an offset of 1 MHz offset and has 5 mW of power dissipation. A complementary series coupled quadrature VCO (S-QVCO) is also implemented with measured phase noise of -114.1 dBc/Hz at an offset of 1 MHz from 3.5 GHz center frequency. The operating range of the designed S-QVCO is 3.05-4.62 GHz and has 2.6 mW power dissipation. A simple high resolution novel PFD is designed for high frequency signal detection and low jitter phase locked loop applications. The proposed PFD design can operate over a wide range of frequencies from 10 kHz to 6 GHz and can detect phase differences for inputs as small as 125 fs for all frequencies of operation and for all process corners.
