ENGLISH ABSTRACT: Rapid Single Flux Quantum (RSFQ) logic cells are discussed, and new cells developed. The expected yield of every cell is computed through a Monte Carlo analysis, and where necessary these cells are optimized for use in a complex system. A mathematical study of the Josephson junction and SQUIDs (Superconducting Quantum Interference devices) as switching elements precede a discussion on the operation of RSFQ and COSL (Complementary Output Switching Logic.) These logic families are implemented in low temperature niobium technology, and require liquid helium cooling. A 10 GHz oversampling delta modulating analogue-to-digital converter is then designed and constructed using RSFQ and COSL building blocks in a hybrid configuration. The design emphasis is on devising ways to test the operation of RSFQ with limited equipment. Yield analysis procedures on the complex system are discussed, followed by a detailed discussion on the circuit layout and layout problems. Software routines are developed to calculate the required dimensions of layout structures. AFRIKAANSE OPSOMMING: Rapid Single Flux Quantum (RSFQ) logiese selle word bespreek, en enkele nuwe selle word ontwikkel. Die verwagte opbrengs, of kans dat 'n sel sal werk, word bereken deur 'n Monte Carlo analise. Waar nodig word selle met behulp van die analise verbeter vir gebruik in 'n komplekse stelsel. 'n Wiskundige studie van die Josephson-vlak en SQUIDs (Superconducting Quantum Interference devices) word gevolg deur 'n bespreking oor die werking van RSFQ en COSL (Complementary Output Switching Logic.) Hierdie logiese families word geïmplementeer in laetemperatuur niobiumtegnologie, en vereis vloeibare helium-verkoeling. 'n Deltamodulerende analoog-na-digitale omsetter met 'n intree-monstertempo van 10 GHz word ontwerp en vervaardig met 'n hibriede samestelling van RSFQ en COSL boublokke. Die ontwerp fokus op maniere om die werking van RSFQ teen 10 GHz te kan toets met die beperkte toerusting wat beskikbaar is. Opbrengsanalise op die komplekse stelsel word bespreek, gevolg deur 'n volledige bespreking van die stroombaanuitlegprosedure en uitlegprobleme. Roetines word in sagteware ontwikkel om die nodige dimensies van uitlegstrukture te bereken. 2012-08-27T11:34:49Z 2012-08-27T11:34:49Z 2001-03 Thesis http://hdl.handle.net/10019.1/52057 en_ZA Stellenbosch University 152 p. : ill. application/pdf Stellenbosch : Stellenbosch University |
