Design of wein bridge oscillator
WebDr. Babasaheb Ambedkar Technological University Lonere, Raigad, Maharashtra 2024 EXPERIMENT NO:6 TITLE: WEIN BRIDGE OSCILLATOR AIM: To design and set up a Wein Bridge oscillator using JFET and to observe the sinusoidal output waveform. APPARATUS: Sr. No Name Range / Value Quantity 1 Regulated D.C (0-20 Volts) 1 … WebDesign of a Wein bridge oscillator can be commenced by selecting a current level for each arm of the bridge. This should be much larger than the op-amp input bias current. Resistors R 3 and R 4 can then be calculated using the estimated output voltage and the closed-loop gain.
