Consider the circuit given in the above figure. Assume that C₁, C2, and C3 are large capacitors and they are short in AC, and open in DC operation. Note that RE1+RE2=4.3kn. a) Determine the DC operating point (Ic, VCE) and the small-signal parameters for the amplifier. b) Draw the small signal equivalent of the circuit. Find the values of R₁1 and Re2 so that the overall voltage gain (vo/Vsignal) is -20V/V. c) Find the input and output resistance values for this amplifier.
