Asynchronous design has been an active area of research since at least the mid 1950's, but has yet to achieve widespread use. We examine the benefits and problems inherent in asynchronous computations, and in some of the more notable design methodologies. These include Huffman asynchronous circuits, burst-mode circuits, micropipelines, template-based and trace theory-based delay-insensitive cir...

This paper provides a novel hierarchical control for VSI-based microgrids. The advantage of the provided control scheme is to maintain the frequency and voltage stability and load sharing against large-signal disturbances. A hierarchical control, consisting of three levels, is described. A new control loop based on PI controller, is presented. The new control loop has a great impact on increasi...

The paper presents current adder and subtractor circuits based on cascode current mirror with improved linearity and wide linear range. The proposed circuits can be used for analog signal processing applications such as amplifiers, operational transconductance amplifiers (OTA), Gm-C filters, etc. In the proposed circuits, cascode current mirror topology is employed to improve current mirroring ...

Power dissipation in CMOS circuits is heavily dependent on the signal properties of the primary inputs. Due to uncertainties in speciication of such properties, the average power should be speciied between a maximum and a minimum possible value. In this paper, we present a novel statistical approach to accurately estimate the maximum and minimum bounds for average power of sequential circuits u...
