SWITCHED CAPACITOR OSCILLATOR

A switched capacitor oscillator is constructed by providing a resonator network with a comparator as a nonlinear feedback element by connecting the input of the comparator to the output of a first operational amplifier of the filter and connecting the output of the comparator to the input network. A...

Beschreibung
Zusammenfassung:	A switched capacitor oscillator is constructed by providing a resonator network with a comparator as a nonlinear feedback element by connecting the input of the comparator to the output of a first operational amplifier of the filter and connecting the output of the comparator to the input network. Also disclosed is a startup network for the oscillator and an input network which derives an input from a reference voltage in order to eliminate supply voltage noise and provide precision control of amplitude.
