2. 1. Digitally controlled analog multiply-accumulate units

   Author : Mattias Duppils; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis is about digitally controlled analog multiplier-accumulator (MAC) units and their utilization in communications applications. These units are implemented as switched-capacitor circuits, designed with switches (MOS transistors), capacitors (MOS transistors), and amplifiers (MOS transistors); using a CMOS technology.

4. 2. Superconductor Digital Signal Processor

   Author : Irina Kataeva; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rapid Single Flux Quantum logic RSFQ ; multiuser detector; VHDL; Multiply-Accumulate Unit; Successive Interference Canceller;

   Abstract : Superconductor digital technology based on Rapid Single Flux Quantum logic (RSFQ) offers more than 50 times gain in speed and more than 100 reduction in power consumption over mainstream CMOS devices. However, the necessity of cooling down to 4 K and modest degree of integration density currently available mean that employing RSFQ is reasonable only for the tasks that are impossible or ineffective to implement in CMOS technology.

5. 3. Design of superconductor digital circuits for a 30 GHz DSP and for interface to qubits

   Author : Samuel Intiso; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VHDL; thermal; RSFQ; noise temperature; Time-delay Optimization; WCDMA; Hierarchycal memory; DSP;

   Abstract : Superconducting digital technology based on Rapid Single Flux Quantum logic (RSFQ) is a digital technology characterized by high speed, low power consumption and low operational temperatures. RSFQ is attractive for many applications and in particular for high frequency Digital Signal Processing (DSP) and for digital control of mK devices like superconducting qubits. READ MORE

6. 4. Multi-Mode Datapath Circuits for Flexible and Energy-Efficient Computing

   Author : Tung Hoang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; precision; power gating; accelerator; Multi-mode; energy efficiency;

   Abstract : Tailored to run domain-specific applications under very strict constraints on, for example, real-time performance and power dissipation, embedded systems rarely can be implemented on general-purpose computing platforms. Rather, the embedded processor's architecture and implementation technology should be fine tuned to the needs of the particular embedded system. READ MORE

7. 5. Experimental Verification of Superconductor Digital Circuits

   Author : Henrik Engseth; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heatload; MCM; high frequency test; RSFQ; Superconductivity;

   Abstract : Superconducting digital technology based on Rapid Single Flux Quantum logic (RSFQ) offers more than 50 times advantages in speed and $100$ times less power consumption than today's mainstream semiconductor electronics. This technology is attractive for many applications and in particular for Digital Signal Processing (DSP) for multi-user detection in a 3G wireless systems being developed at Chalmers University.
