    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oscillator design efficiency; phase noise; impulse sensitivity function; design methodology; amplitude control; frequency tuning; oscillator; describing function;

    Sammanfattning : Oscillators are present in most electronic equipment where they provide timing information, for example as sampling clocks in analog-to-digital converters or as radio carriers in wireless communications. To design an oscillator, we must have knowledge of the properties and the operation of oscillators. LÄS MER

    Sammanfattning : Today's complex electronic systems with billions of transistors on a single die are enabled by the aggressive scaling down of the device feature size at an exponential rate as predicted by the Moore's law. Digital circuits benefit from technology scaling to become faster, more energy efficient as well as more area efficient as the feature size is scaled down. LÄS MER
