10–53 There is no initial energy stored in the circuit in Figure P10–53.

(a) Transform the circuit into the s domain and formulate node-voltage equations.

(b) Solve these equations for V2ðsÞ in symbolic form.

(c) Insert an OP AMP buffer at point A and solve for V2ðsÞ in symbolic form. How did inserting the buffer change the denominator and, therefore, the location of the poles?

(d) Using both separate circuits (with and without the OP AMP), select values of R1, R2, C1, and C2 to locate a pole at −10 krad=s and a second pole at −100 krad=s. Evaluate the two approaches and give pros and cons for each design.
