Abstract :
In the present work we propose a versatile CCII+ based structure which can be used both as a second-order band-pass/low-pass filter and as a variable frequency sinusoidal oscillator, performing adequately in both applications. The chosen configuration exhibits an easy control of the main parameters, such as characteristic frequency, quality factor and voltage gain. Experimental results verify the expected structure behaviour and capabilities.
