The purpose of this paper is to show that exists a close relationship between
some CCII+ based sinusoidal oscillators and the RC active second order
oscillators with a single VCVS. These structures with CCII+ may be derived from
the classic Wien-bridge oscillator, and four of them exhibit practical interest.
They are canonical, the oscillation condition can be adjusted by a single
resistor, and fu... hiện toàn bộ
