The following figure shows a voltage amplifier having an input resistance Ri, an input capacitance Ci, a gain factor μ, and an output resistance R0. The amplifier is fed with a voltage source Vsig having a source resistance Rsig, and a load of resistance RL is connected to the output. Assuming Rsig = 20 kΩ, Ri = 100 kΩ, μ = 144 V/V, RO = 200 Ω, RL = 1 kΩ, and the capacitor Ci = 340 pF. Find the magnitude of the total transfer function |T(ω)| = |Vout (ω)/Vsig (ω)|, where ω = 2π124×103 rad/sec. Express your answer in dB
