Compare the circuit of with a circuit implemented by

Question

(a) Compare the circuit of Example with a circuit implemented by cascading two amplifiers with individual dc gains  A₁₀=A₂₀= √|A₀|^V/V. (b) Repeat, but for the circuit of Example 8.16.

Example

A current-output DAC is fed to a CFA having z₀ = 750 kΩ, f_b = 200 kHz, and r_n = 50 Ω. Assuming R = 1.5 kΩ and C_n = 100 pF, find C_f for φ_m = 45?. Verify with PSpice.
