RC Oscillators with Two Operational Amplifiers with Precision Phase Shift between Two Outputs
(Společnost pro radioelektronické inženýrství, 1996-12)In some instruments oscillator with precision 90° phase shift of output signals is needed. In this article a new type of RC oscillators with precision 90° phase shift between two low impedance output signals is described. ...
