Abstract :
Two fully differential low-voltage MOSFET-C 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
