A low-voltage fully differential MOSFET-C bandpass-based voltage-controlled oscillator for frequency tuning
A low-voltage fully differential MOSEFT-C bandpass-based voltage-controlled oscillator for the purpose of frequency-tuning of filters is proposed. This oscillator is guaranteed to start oscillating and provide well-controlled amplitude. Experimental filters and the filter tuning circuit are designed to demonstrate its use. The performance of this circuit is shown by experimental results.
