Abstract :
A method of realizing switched capacitor sinusoidal oscillators with a very stable frequency of operation is presented. The oscillating frequency is dependent only on the external clock frequency. The method is arrived at through the n-path filtering principle. Experimental results show the excellent stability and tunability properties of the oscillator
