Abstract
This thesis proposes an approach of investigating electrical and noise parameters of subcomponents inside a fully differential system. To find the single-ended noise parameters, two sets of single-ended noise-parameter measurements and one set of S-parameter measurement are performed. A proof-of-concept PCBs is designed, fabricated, and tested after the algorithms are verified using Matlab. The circuit is designed to have a bandwidth from 500 MHz to 1.5 GHz and be unconditionally stable at all frequencies. The designed circuit has the gain of 9.4 dB at 500 MHz and 9.5 dB at 1.5 GHz in schematic simulations, while in measurements, it has the gain of 8.1 dB at 500 MHz and 4.3 dB at 1.5 GHz. The minimum noise figure is 2.4 dB at 500 MHz and 2.4 dB at 1.5 GHz in simulations, while in measurements, it is 3.1 dB at 500 MHz and 3.2 dB at 1.5 GHz. This thesis presents schematic and measurement results for the electrical and noise parameters. The measurement results are analyzed in Matlab and compared with the relevant single-ended measurement results to verify the operation of the method.
