Hi, I want to find cutoff frequency of the two attached circuits. I just want to know is there any quicker way to find it. For the circuit2 I got it as 1/(2*pi*R*C) but I don't see the same in simulation, so I want to verify it with someone.
Circuit1:
Circuit2:
The cutoff frequency is defined as the frequency where the amplitude of H(jω) is 1/√2 times the DC amplitude (approximately -3dB, half power point).
