Abstract :
Two MOSFET-C low-voltage fully differential voltage-controlled oscillators for the purpose of frequency-tuning of filters are proposed. These two oscillators are guaranteed to start oscillating and provide well-controlled amplitude. The performance of these two circuits is demonstrated by simulation results.
