Novel sinusoidal oscillator employing grounded capacitors

An earlier single-resistance-controlled oscillator (s.r.c.o.) with grounded capacitors employs three operational amplifiers (o.a.); the new s.r.c.o. proposed here employs only two o.a.s and a reduced number of resistors. The proposed s.r.c.o. may be adopted for voltage-controlled-oscillator realisation. In addition, the new circuit may also be employed for the generation of very-low-frequency oscillations. The circuit appears to be suitable for integrated-circuit implementation.
