Question

having a de is to cascade Op amps wi Write an Figure P2.42 243. The objective of this probiem is to investigate the effects of finite gain, finite input impedance, and nonzero output impedance of the op amp on the inverting amplifier. Consider the effects ex 248. A cert the circui, including the op-amp model, shown in Figure P2.43. amp has a d (a) Derive an expression for the circuit voltage gain o/to scale. If t Sketch the E Evaluate your expression for Aot-10, R--İ Mo. having a dr R,-25 Ω. R.-1kQ, and R. 10 kn. Compare this result to the gain with an ideal op amp the magnitud closed-loop Section (b) Derive an expression for the circuit input impedance 4/i, . Evaluate your expression for AOL-10, Au-1 Mn.
