Variable Frequency RC Oscillators Audio oscillators produce waves having frequencies from about 20Hz to 20kHz (the audio spectrum) and up to about 100kHz for ... phase shift oscillator is obtained by using op amp buffers to reduce the loading on the phase shift filter circuits.

Hence RC phase shift oscillator is popularly used as an audio oscillator. For generating different audio frequencies, variable air capacitors are used as circuit elements C in the phase shift network. Such capacitors vary over capacitance range of about 10:1, typically from 40 pF to 450 pF.

The oscillator core is implemented using the Burr-Brown UAF42 state variable filter, U4. A range switch, SW1, is added with both fixed and variable settings. All ranges use the UAF42's internal 1nf integrating capacitors, shown in parentheses on the schematic diagram.

C can be a variable capacitor if a variable frequency oscillator is essential. Remember that the tapping does not have to be at exactly the centre of the winding, and that for example, the circuit will function completely well while using primary of an I.F. trans-former. Phase-Shift Oscillator

A. Phase-Shift Oscillator Frequency of the oscillator: (the frequency where the phase shift is 180º) Feedback gain β= 1/[1 – 5α2 –j (6α–α3) ] where α= 1/(2πfRC) Feedback gain at the frequency of the oscillator β = 1 / 29 The amplifier must supply enough gain to compensate for losses. The overall gain must be unity.
