Many RC oscillators use advanced circuit in phase shift unit. It uses a voltage feedback amplifier, of which the gain will get a sharp decline in a higher frequency and stop oscillation before reaching the desired frequency. That is the reason why voltage feedback amplifier has poor phase characteristics. The RC oscillator composed of high-frequency IC HA502..
