6. Integrated Variable-Gain and CMOS Millimeter-Wave Amplifiers
Sammanfattning : Variable Gain Amplifier finds extensive use in the high frequency demonstrators specially those operating in the millimeter-wave regions and beyond where the incoming RF signal level can have wide variations. To maintain a constant signal level an IF VGA has been designed that can offer a dynamic variation of gain as much as 45 dB together with a high maximum gain and a low noise figure. LÄS MER
7. Design and Analysis of Highly Linear Integrated Wideband Amplifiers
Sammanfattning : This dissertation deals with techniques for designing integrated amplifiers with high linearity. Amplifiers with operating frequencies from Audio to RF have been built. An enhanced feedback configuration, capable of very low distortion, is presented. LÄS MER
8. Silicon nanowire based devices for More than Moore Applications
Sammanfattning : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. LÄS MER
9. Monolithic Integrated Oscillators - Phase Noise Analysis and Inductor Modeling
Sammanfattning : This doctoral dissertation studies voltage controlled oscillators (VCOs) that operate at low supply voltages. Due to smaller transistor sizes and lower supply voltage ratings with every new CMOS technology, voltage headroom is diminishing. LÄS MER
