A new circuit topology for quadrature signal generation is presented. In the proposed circuit two identical negative-resistance oscillators are coupled to each other via capacitors in such a way that quadrature signals are ...

A method for multiphase signal generation by means

of coupling several identical cross-connected LC-VCOs via

capacitors is presented. An analysis is presented which shows

that there is a 180/N degrees ...

In this paper challenges observed in 65nm technology for

circuits utilizing subthreshold region operation are presented.

Different circuits are analyzed and simulated for ultra low

supply voltages to find the best topology...

This paper presents the results of an experimental investigation of power generation from low-grade heat sources based on an organic Rankine cycle (ORC). Iso pentane was used as the ORC working fluid in this study. The heated water with natural gas...
