  1. 1. Digitally controlled analog multiply-accumulate units

    Författare :Mattias Duppils; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : 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. LÄS MER

  3. 2. Customization for an Energy-Efficient Embedded Processor with Flexible Datapath

    Författare :Tung Hoang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integration.; Embedded; Multiply-ACcumulate; Flexible; Energy;

    Sammanfattning : Due to diversified demands of customers, embedded processor datapaths have been extended to accept many functional units, thus growing more complex and energy inefficient. For this reason, it is necessary to carefully analyze the characteristics of the specific embedded applications and fine-tune the hardware implementation. LÄS MER

  4. 3. Superconductor Digital Signal Processor

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

    Sammanfattning : 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. 4. CMOS mixed analog/digital building blocks for signal processing

    Författare :Mattias Duppils; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : A mixed analog/digital multiply-accumulate unit is presented. The unit is composed of the multiplying D/A converter and a polarity switching network. It is featured by an analog continuous-time input port, a discrete­time output port, and a digital input port for the quantized multiplying coefficient. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
