Hey experts,
im trying to construct a single transistor colpitts oscillator circuit using LC circuit as shown in the figure, to detect the change in frequency when varying the value of inductor
According to f=1/2*pi*(L*Ct)^1/2
Where Ct= C1*C2/C1+C2
so C1=C2=47ηF
and L1=47μH
Hence oscillating frequency should be 150 Khz
However, the circuit didnt oscillate when connecting it in bread board
i have tried many schematic circuits on the internet but it seems that the feedback circuit is not connected to the transistor (( amplifier circuit )) for some reason
may any of the great engineers help me connecting this circuit
