This paper presents a new approach to global clock distribution in which traditional tree-driven grids are augmented with onchip inductors to resonate the clock capacitance at the fundamental frequency of the clock node. Rather than being dissipated as heat, the energy of the fundamental resonates between electric and magnetic forms. The clock drivers must only provide the energy necessary to o...

Homomorphic encryption has been used for supporting simple aggregations, numeric calculations on encrypted data as well as for private information retrieval. Recently, theoretical breakthroughs on homomorphic encryption resulted in fully homomorphic encryption, which is able to compute arbitrary functions on encrypted data. As a result, homomorphic encryption is generally believed to be the hol...

We consider a one dimensional stochastic control problem that arises from queueing network applications. The state process corresponding to the queue-length is given by a stochastic differential equation which reflects at the origin. The controller can choose the drift coefficient which represents the service rate and the buffer size b > 0. When the queue-length reaches b, the new customers are...

This paper describes a CMOS analogy voltage supper buffer designed to have extremely low static current Consumption as well as high current drive capability. A new technique is used to reduce the leakage power of class-AB CMOS buffer circuits without affecting dynamic power dissipation. The name of applied technique is TRANSISTOR GATING TECHNIQUE, which gives the high speed buffer with the redu...

This paper presents a practical implementation and measurement results of power-efficient chip performance optimization, utilizing low-cost indirect methods to support self-X properties (self-calibration, self-healing, self-optimization, etc.) for in-field optimization analog front-end sensory electronics with XFAB 0.35 µm complementary metal oxide semiconductor (CMOS) technology. The reconfigu...

The design of a fully integrated upconversion mixer for use in a UMTS transmitter is presented. UMTS is the system which is developped for wireless transmission with high datarates. It uses Code Division Multiple Access to separate users of the same channel at the same time. The transmitted signal of one user has a nonconstant envelope due to filtering that is applied to limit the bandwidth. In...

A HBC derivative bearing six branched, space-demanding, alkyl side chains containing ether linkages has been synthesized and its thermotropic properties were investigated by polarization optical microscopy (POM) and differential scanning calorimetry (DSC). To our surprise, this molecule can respond to electric fields, and the influences of alternating current (AC) and directing current (DC) ele...
