Hi, I am currently trying to construct an oscillator using a sallen-key low pass filter and is using LTSpice to simulated the circuit. Based on the transfer function of the circuit, I calculate the value of K(gain) which is equals to 3 exactly. The output of the circuit is zero when the input is grounded, and the values of C=C1=C2=10u and R=R1=R2=10k. But, the output of the circuit is zero when i try to simulate.
Any suggestions or advises?
