Hi,
How to implement a function like H(s) = 1 + as + bs^2 ?
laplace_nd in cadence spectre exits complaining that the order of denominator is not  same as numerator order.

Thanks

In case you want your original transfer function rather than Geoffrey's, you can get it by using the laplace function to implement a voltage-to-current converter with Geoffrey's, and then place it in the feedback path of an ideal opamp configured as an inverting amplifier. That will act to invert the transfer function.
