Low phase noise frequency synthesizers are of primary importance in modern RF communication systems to maintain signal integrity. Since current technologies are going mobile, without much reduction of operating speed, a low phase noise TDC less digital PLL is proposed in this thesis. A dual edge...

Alarm systems are critical assets of modern industrial plants to assist operators in managing plant upsets and hazardous situations. A good alarm system must detect abnormalities and warn the operators promptly and yet at the same time not mislead, overload or distract the operators. However, in...
