This paper describes the thermal and electrical characteristics of GaN on SiC power transistors that have been designed to be mounted directly upon a CMOS driver integrated circuit. In order to maximize the customer value proposition and minimize the cost implications of using a high capability GaN on SiC die, the hybrid device has to exhibit substantial performance and convenience advantages o...

Current scanning technology for the brain and heart requires electrodes to be placed on the surface, with a wire connected to each electrode. Because the electrodes are large, it is impossible to achieve a high sampling resolution of the signals from the tissue being scanned. Silicon based structures are not very suitable for this application. They have a rigid planar surface which prevents the...

Purpose – The demand for higher bandwidth has resulted in the development of mm-wave phased array systems. This paper explores a technique that could be used to feed the individual antennas in a mm-wave phased array system with the appropriate phase shifted signal, to achieve required directivity. It presents differential Colpitts oscillators at 5 GHz and 60 GHz that can provide differential ou...

This paper proposes a methodology for the parametric design of operational transconductance amplifiers. In the proposed methodology, amplifier sizing is performed in two stages: an equation-based design scheme performs an approximate design, followed by optimization of the design results with genetic algorithms. The feasibility of this method was investigated with extensive simulation. For demo...

T h e technique of mirror biasing i s introduced and applied to a very high gain two stage CMOS cascode op-amp, in order to desensitize i ts output voltage to bias variations. Various performance metrics like low frequency common mode and power supply rejection ratios, slew rate and the sensitivity of the systematic offset are substantially improved. The improved performance i s theoretically p...

A novel logic family, called charge recycling differential logic (CRDL), has been proposed and analyzed. CRDL reduces power consumption by utilizing a charge recycling technique with the speed comparable to those of conventional dynamic logic circuits. It has an additional benefit of improved noise margin due to inherently static operation. The noise margin problem of true single-phase-clock la...
