Take a simple RC circuit, it's time constant is just RC, Take an op-amp. An op-amp by default is like a LPF in most of the cases. Hence, it will have a cut-off frequency where it's like lies. That pole is nothing but 1/time constant of the op-amp. black country coroner\u0027s court

RC Discharging Circuit Tutorial & RC Time Constant

WebThe time constant is a time period determined by the circuits R and C values. It is measured in seconds and denoted with the variable (τ) tau. Tau is very easy to find since τ = R×C. An RC circuit’s time constant is useful because it directly relates the values of R and C to the capacitor voltage.
