HI all! I'm a student, I have a problem! I want to design a oscillator circuit at 50khz frequency.
what should I do? use a transistor or op-amp circuit and a positive feedback!
and may use give me some name of a transistor or op-amp
HiHI all! I'm a student, I have a problem! I want to design a oscillator circuit at 50khz frequency.

please help me!
any help will be grate!
Thank you so much!
thank! all! but if a real circuit! how many prolems are the best importance?? the problem with transistor and op-amp!
Hi Thanhbut may you help me again! the frequency is not good! the frequency that I need is 50khz!
when I simulate with my circuit the frequency I recieved is about 20khz! I don't known why?
help me!
any help will be great!
LvW! I don't understand what u mean! this is Vout result of mine!
Vo = V(D1n4002) * (3*R8*C1*s + R8*R8 + c1*c1*S*s) / (R8*R8) + (C1*C1*s*s))
V(D1n4002) is threshold voltage!
is it true??please help me!
Thank!

but there is only one of two series of (D1, D2, R3), (D3, D4, R4) the current throught at any point of time! so the other has a huge impedance!
Hi againbut the current throught only one of two circuit of (D1, D2, R3) or (D3, D4, R4) at every period of time! so the other like seem a huge impedance!
I'm sorry goldsmith. it is difficult for me to explain because of my english skill.
I have simple idea is when two resistor(r1, r2) in parallel. if r1>> r2 the value of (r1//r2) ~= R2.
Thank you!
