Prelab Work
1] The circuit shown in Figure 1 uses a 1Ii'oltage—current feedback circuit which is
bingighted in the box. Perform a DC analysis on the entire circuit to find L: and gm. Assume that ii = lflfl. Figure 1 2} Sketch the circuit difierently to highlight the Fcedfctcrctti and feedback
components for this feedback amplifier (assure: that capacitors are almost short—
circuits at the operating frequency}. 3] Use the Miller’s theorem to determine the ME bandwidth of the circuit. 4] Find the trans—impedance gain AMP.“ = an’fiin’ for the open—loop circuit [asstme
that capacitors are almost short-circuits at the operating frequency}.

5) Find the closed-loop midband (i.e., assuming that capacitors are almost short-
circuits at the operating frequency) gain AR,closed = Vowim for the feedback
amplifier in Figure 1.
6) Find the closed-loop input and output resistances of the circuit in Figure 1.
