I want to design a sine wave generator circuit which should generate frequencies from 2KHz to 8KHz.
Supply voltage is in the range of 700mV to 25V. Tolerance of frequency is 50Hz.
I designed the circuit using transistor (BC107) but the circuit works (generates frequency) only after the supply voltage exceeds 6V.
And also the frequency tolerance is also not good.
Can any one please suggest me a solution for this
Circuit I used is shown below
R1 = 47Kohm,
R2 = 10K
Rc = 2.2K
Re = 680ohm
Ce = 22uF
C = 10nF
R = 2.4K
Cc = 1uF
Transistor is BC107
