Testing two design pixel detector readout components for the phase I upgrade of the CMS experiment

During Phase I (2018) of the Large Hadron Collider (LHC) upgrade, the Compact Muon Solenoid (CMS) pixel detector will need to handle a much higher data volume due to the doubling of the luminosity as well as the planned increase in the number of pixel modules. To meet this challenge, the readout scheme will be changed to digital readout and the readout frequency will be increased. The design of the new readout system includes the use of a voltage control oscillator (VCO) and data serializers. A possible VCO design was developed by the Paul Scherrer Institute. This thesis documents the computerized simulation of this design which predicted that it would perform adequately. Then, three prototype samples were built and tested experimentally. To determine radiation hardness, they were irradiated with ${^60}$Co in 10 doses of 50 KGy, each. The measurements showed that this circuit will keep working under high doses of irradiation. The serializer has also been designed and studied via simulation determining its timing parameters. The circuit design performs as expected
