Found in a Philips' 1968 documentation, this circuit is slightly different from the previous one. The components are also from the era, and modern equivalents can be used.
Other operational amplifiers can be used on this unit gain amplifier. The circuit is from the 1993...
In this oscillator a phase shift network formed by C1, C2, C3 and R1, R3, R4 determine the fase...
This basic buffer circuit can be implemented with other operational amplifiers. The circuit is...
