    Notes: Abstract In this paper, the strong inversion MOS analog of the recentlyproposed class of log-domain filters, or translinear filters, isproposed.The dynamic √ -domain principle, or dynamicvoltage-translinear principle, exploits the quadratic law, describing theMOS transistor in the strong inversion region, both to perform an expandingV-I conversion of the capacitor voltages and to implement multiplicationsand square roots of currents based on the voltage-translinear principle.Thepresented theory is applied to the design of a current-controlledtwo-integrator oscillator. Experiment results of a pure CMOS test IC showthe feasibility of the √ -domain principle. The realized oscillatorhas a THD of −42 dB and is linearly frequency tunable across 1.3decades.

    An integratable second-order compensated bandgap reference for 1V supply (1995)
    Springer
    Analog integrated circuits and signal processing 8 (1995), S. 69-81 
    Details
    ISSN: 1573-1979
    Keywords: low-voltage ; low-power ; bandgap reference ; design theory ; voltage reference
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract A new systematic approach is used for the design of bandgap references. A linear combination of two base-emitter voltages is taken to compensate implicitly for the temperature behavior of these base-emitter voltages. To reach optimum circuit performance with respect to accuracy and power, systematic design procedures are used. The realized bandgap reference circuit is completely integratable and operates from a supply voltage of only 1V. The output voltage is approximately 194 mV and has an average temperature dependency of 1.5ppm/°C in the range of 0°C to 100°C. The circuit has been realized in a bipolar process withf t ⩾ 5 GHz. The total amount of capacitance is approximately 150 pF and the current consumption is about 100µA.

    Design of a processing board for a programmable multi-VSP system (1993)
    Springer
    The journal of VLSI signal processing systems for signal, image, and video technology 5 (1993), S. 171-184 
    Details
    ISSN: 1573-109X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract In this article we describe a programmable multi-processor system based on the Philips Video Signal Processor (VSP) for real-time video applications and the environment to program it. The main distinctive characteristic of this setup is the full programmability of both its computation and communication elements. Moreover, a versatile tool-set automates the programming of these elements. As a consequence, short design-cycles are achieved and the system is well suited for rapid prototyping. In this article we mainly concentrate on the design of the processing board of the system and the corresponding programming tool.

    A Low-Power Class-AB Negative-Feedback Output Amplifier for a 1 V LW Receiver (1999)
    Springer
    Analog integrated circuits and signal processing 20 (1999), S. 63-75 
    Details
    ISSN: 1573-1979
    Keywords: low voltage ; low power ; systematic analog design
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract The design and the measurement results are presented of a low-voltage (1 V) class-AB negative-feedback output amplifier. The amplifier is designed for use in a single-chip LW receiver, which can be put completely in the ear, supplied by a 1 V power supply and is capable of driving a load with an impedance of 30 Ω. The maximum output current of the amplifier is approximately 2.5 mA and its quiescent current is approximately 100 μA. This high efficiency is obtained by means of biasing two of the three amplifying stages in class-AB operation. With the aid of negative feedback, the total harmonic distortion for a single 1 kHz tone at 1 mA level is kept below 1%. The output amplifier is integrated in a bipolar process which has vertical NPN transistors with a maximum f T of 5 GHz and lateral PNP transistors with a maximum f T of 20 MHz.
