Design an rc phase shift oscillator to generate 10Khz sine wave with 10V peak-to-peak amplitude. Determine suitable ratings for the zener diodes You are provided by : i)Three 1nF capacitors and a bypass capacitor ii) A BJT with hfe= 120 and hre = 3k ohms iii) Two zener diodes of equal ratings iv) Assortment of resistors to choose from
fo = (1/sqr(6) (1/(2 PI R C) Volt gain at fo is to be -29 Approximate gain of amplifier is Rc/Re for design input of 10sin((1/sqr(6)RC) The objective is to decrease gain as signal increases until design output, your emitter capacitor may be wrong, should couple input, use zener's somehow to limit gain.
