Hi all, im wondering if someone could point me in the right direction.
i have been tasked with designing a wien bridge oscillator circuit that is required to have an output of 14.6kHz.
the circuit must also use a 741 op amp with a +/- 12v.
However after using the formula 1/(2*pi*CR) to calculate component values, when testing, the output frequency seems limited to around 11kHz?
is there anyway that would help me to achieve the desired output frequency as it seems that adjusting the RC circuit values doesnt have much of an effect?
thanks in advance.
