    In this paper, concise formulas for the intermodulation distortion of a bipolar common-emitter amplifier stage with arbitrary emitter impedance and input matching network are presented. These expressions provide quantitative insight in the influence of transistor properties, emitter degeneration and input power matching on distortion. Only a small set of measurable transistor parameters is needed.... View full abstract»

    This paper presents a new control scheme for a Class DE inverter, that is, frequency modulation/pulsewidth modulation (FM/PWM) control. Further, the FM/PWM controlled Class DE inverter is analyzed and we clarify performance characteristics. Since the FM/PWM controlled inverter has two control parameters, namely, the switching frequency and the switch-on duty ratio, it has one more degree of freedo... View full abstract»

  • Analysis and design of class E amplifier with shunt capacitance composed of nonlinear and linear capacitances

    The Class E amplifier requires exact shunt capacitance to achieve optimum operation. Most Class E amplifiers are usually constructed by adding an external capacitor to the output capacitance of the power transistor in order to obtain the total required shunt capacitance. The output capacitance of the power transistor is nonlinear and the external capacitance is linear. Therefore, neither design eq... View full abstract»

    We present a transmitter for a scalable multiple-access inter-chip link that communicates binary activity between two-dimensional arrays fabricated in deep submicrometer CMOS. Transmission is initiated by active cells but cells are not read individually. An entire row is read in parallel; this increases communication capacity with integration density. Access is random but not inequitable. A row is... View full abstract»

    We present a receiver for a scalable multiple-access inter-chip link that communicates binary activity between two-dimensional arrays fabricated in deep submicron CMOS. Recipients are identified by row and column addresses but these addresses are not communicated simultaneously. The row address is followed sequentially by a column address for each active cell in that row; this cuts pad count in ha... View full abstract»

    We present results for a scalable multiple-access inter-chip link that communicates binary activity between two-dimensional arrays fabricated in deep submicrometer CMOS. Capacity scales with integration density because an entire row is read and written in parallel. Row activity is encoded in a burst: The row address followed by a column address for each active cell. We predict the distribution of ... View full abstract»

    We develop an accurate analytical expression for the propagation delay of submicrometer CMOS inverters that takes into account the short-circuit current, the input-output coupling capacitance, and the carrier velocity saturation effects, of increasing importance in submicrometer CMOS technologies. The model is based on the nth-power-law MOSFET model and computes the delay from the charge delivered... View full abstract»

  • Testing stability of 2-D discrete systems by a set of real 1-D stability tests

    Publication Year: 2004, Page(s):1312 - 1320

    Stability of a two-dimensional (2-D) discrete system depends on whether a bivariate polynomial does not vanish in the closed exterior of the unit bi-circle. The paper shows a procedure that tests this 2-D stability condition by testing the stability of a finite collection of real univariate polynomials by a certain modified form of the author's one-dimensional (1-D) stability test. The new procedu... View full abstract»

    This paper considers the fundamental problem of passive multidimensional Kirchhoff networks for linear time-varying systems that are suitable for wave digital filter discretization. An explicit solution, subject to the validity of a commutativity condition, is given in the linear time-varying case for the feasibility of representation of the coupled inductor, the crucial dynamic multiport in the n...

    Noise figure (NF) is a commonly used system parameter that quantifies the degradation in the signal-to-noise ratio (SNR) as the signal passes through a receiving system. Because of the difficulty in defining the SNR, NF depends on how the SNR is computed and the underlying assumptions that are made. Existing NF measures and their shortcomings are explained. A new NF suitable for a digital communic... View full abstract»

  • On the ultimate limits of chaos-based asynchronous DS-CDMA-I: basic definitions and results

    The ultimate limits of chaos-based asynchronous direct-sequence code-division multiple access systems are investigated using the concept of capacity taken from information theory. To this aim, we model the spreading at the transmitter and the sampling of the incoming signal at the receiver with a unique linear multi-input multi-output transfer function. We then assume the existence of a coding/dec... View full abstract»

    The theoretical error signal analysis of a sigma-delta (/spl Sigma//spl Delta/) modulator is a difficult problem due to the presence of a nonlinear operation (the amplitude quantization) in a feedback loop. In this paper, new deterministic knowledge on the transfer function of a /spl Sigma//spl Delta/ modulator is established, thanks to some recently observed properties of its state variables. For...

    A frequency-domain small-signal analysis of resonant power converters is presented. In this analysis, the load presented to the ac side of the rectifier is modeled as a time varying resistor. Using conversion matrix techniques and an iterative procedure to find the magnitude and phase of the time-varying resistor, the transfer functions of the converter can be obtained fast and accurately.

    In this paper, a novel true random bit generator (TRBG) based on a double-scroll attractor is proposed. The double-scroll attractor is obtained from a simple model which is qualitatively similar to Chua's circuit. In order to face the challenge of using the proposed TRBG in cryptography, the proposed TRBG is subjected to statistical tests which are the well-known Federal Information Processing Sta...
